Marking Scheme of Accenture Coding Section

The Accenture Coding Questions section consists of two questions that candidates have to complete in 45 minutes. To pass this section, they have to achieve one partial output and one complete output.

Accenture Coding Questions 

The following is a compilation of the type of Accenture coding questions that you’d be encountering.

1. Execute the given function.

def differenceofSum(n.m)

The function takes two integrals m and n as arguments. You are required to obtain the total of all integers ranging between 1 to n (both inclusive) which are not divisible by m. You must also return the distinction between the sum of integers not divisible by m with the sum of integers divisible by m.

Assumption

• m > 0 and n > 0
• Sum lies within the integral range
   

Example

Input:
m = 6
n = 30

Output:
285

• Integers divisible by 6 are 6, 12, 18, 24, and 30. Their sum is 90.
• Integers that are not divisible by 6 are 1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17, 19, 20, 21, 22, 23, 25, 26, 27, 28, and 29. Their sum is 375.
• The difference between them is 285 (375 – 90).
   

Sample input:
m = 3
n = 10

Sample output:
19
 

2. Execute the given function.

def LargeSmallSum(arr)

The function takes an integral arr which is of the size or length of its arguments. Return the sum of the second smallest element at odd position ‘arr’ and the second largest element at the even position.

Assumption

• Every array element is unique.
• Array is 0 indexed.

Note:

• If the array is empty, return 0.
• If array length is 3 or <3, return 0.
   

Example

Input:
Arr: 3 2 1 7 5 4

Output:
7
 

Explanation

• The second largest element at the even position is 3.
• The second smallest element at the odd position is 4.
• The output is 7 (3 + 4).
   

3. Write a function to validate if the provided two strings are anagrams or not. If the two strings are anagrams, then return ‘yes’. Otherwise, return ‘no’.

Input:

Input 1: 1st string
Input 2: 2nd string

Output:
(If they are anagrams, the function will return ‘yes’. Otherwise, it will return ‘no’.)

Example

Input 1: Listen
Input 2: Silent

Output:
Yes

Explanation

Listen and Silent are anagrams (an anagram is a word formed by rearranging the letters of the other word).

4. Perform the following function. 

def Productsmallpair(sum,arr)

This function accepts the integers sum and arr. It is used to find the arr(j) and arr(k), where k ! = j. arr(j) and arr(k) should be the smallest elements in the array.

Keep this in mind:

• If n<2 or empty, return –1.
• If these pairs are not found, then return to zero.
• Make sure all the values are within the integer range.
   

Example

Input:
Sum: 9
Arr: 5 4 2 3 9 1 7

Output:
2

Explanation

From the array of integers, we have to select the two smallest numbers, i.e 2 and 1. Sum of these two (2 + 1) = 3. This is less than 9 (3 < 9). The product of these two is 2 (2 x 1 = 2) Hence the output is integer 2.

Sample input:
Sum: 4
Arr: 9 8 –7 3 9 3

Sample output:
–21
 

5. Perform the function for the given purpose.

For writing numbers, there is a system called N-base notation. This system uses only N-based symbols. It uses symbols that are listed as the first n symbols. Decimal and n-based notations are 0:0, 1:1, 2:2, …, 10:A, 11:B, …, 35:Z.

Perform the function: Chats DectoNBase(int n, int num)

This function only uses positive integers. Use a positive integer n and num to find out the n-base that is equal to num.

Steps

• Select a decimal number and divide it by n. Consider this as an integer division.
• Denote the remainder as n-based notation.
• Again divide the quotient by n.
• Repeat the above steps until you get a 0 remainder.
• The remainders from last to first are the n-base values.
   

Assumption
1 < n < = 36

Example

Input:
N: 12
Num: 718

Output:
4BA

Explanation

Sample input:
N: 21
Num: 5678

Sample output:
CI8
 

6. Execute the function for the given purpose.

When the sum of the digits exceeds a total of 9, a carry digit is added to the right-left of the digit. Execute the function: Int Numberofcarry(Integer num 1, Integer num 2)

Assumption

num1, num2 > = 0

Example

Input:
num1: 451
num2: 349

Output:
2

Explanation

When we add these two numbers from the right to the left, we get two carries. The value of each of the carries is 1. Hence, the output is the total of these two carries, i.e., 2.

Sample input:
num1: 23
num2: 563

Sample output:
0
 

7. The given function has a string (str) and two characters, ch1 and ch2. Execute the function in such a way that str returns to its original string, and all the events in ch1 are replaced by ch2, and vice versa.

Replacecharacter(Char str1, Char ch1, Int 1, Char ch2)

Assumption

This string has only alphabets that are in lower case.

Example

Input:
str: apples
ch1: a
ch2: p

Output:
paales

Explanation
All the ‘a’ in the string is replaced with ‘p’. And all the ‘p’s are replaced with ‘a’.

8. Perform the function: Int operationchoices(int c, int n, int a, int b). This function considers three positive inputs of a, b and c.

Execute the function to get:
(a + b), if c = 1
(a / b), if c = 4
(a – b), if c = 2
(a x b), if c = 3

Example:

Input:
a: 12
b: 16
c: 1

Output:
28

Explanation
C = 1, hence the function is (a + b). Hence, the output is 28.

Sample input:
a: 16
b: 20
c: 2

Sample output:
–4
 

9. Perform the function Int calculate(int m, int n). This function needs two positive integers. Calculate the sum of numbers between these two numbers that are divisible by 3 and 5.

Assumption
m > n > = 0

Example

Input:
m: 12
n: 50

Output:
90

Explanation
The numbers between 12 and 50 that are divisible by 3 and 5 are 15, 30, and 45. The sum of these numbers is 90.

Sample input:
m: 100
n: 160

Sample output:
405
 

10. Execute the function for the given purpose.

Create a matrix and mention the elements in it. Now, divide the main matrix into two halves in such a way that the elements in index 0 are even, the elements in index 1 are odd, and so on.

Then arrange the values in ascending order for even and odd. After this, calculate the sum of the second largest numbers from both even and odd matrices.

Example
The size of the array is 5.
Element at 0 index: 3
Element at 1 index: 4
Element at 2 index: 1
Element at 3 index: 7
Element at 4 index: 9

Even array: 1,3,9
Odd array: 4,7

11. The binary number system only uses two digits 1 and 0.

Perform the function: Int OperationsBinarystring(char* str)

Assumptions

• Return to –1 if str is null.
• The str is odd.
   

Example:

Input:
Str: ICOCICIAOBI

Output:
1

Explanation
The input when expanded is “1 XOR 0 XOR 1 XOR 1 XOR 1 AND 0 OR 1”. The result becomes 1 and hence the output is 1.
 

12. Perform the function Checkpassword (char str[], int n)

Execute the function which happens to be 1 if the str is a valid password or it remains 0.

Conditions for a valid password: 

• The password should have at least 4 characters.
• It should have at least 1 digit.
• It should have one capital letter.
• It should not have any spaces or obliques (/).
• The first character should not be a number.
   

Assumption
The input is not empty.

Example

Input:
aA1_67

Output:
1
 

13. Execute this function Void MaxInArray(int arr[], int length)

This function helps in finding the maximum element in the array. Execute this function to print the maximum element in the array with its index.

Assumptions

• The index in the array for all the elements starts at 0.
• The maximum element is in a different line in the output.
• There has to be only one maximum element.
• The function prints only what is required.
   

Example

Input:
23 45 82 27 66 12 78 13 71 86

Output:
86
9

Explanation
The maximum element is 86 and the array is 9.
 

14. Change frequent character

The function to execute is
ChatFrequentcharacter(Char str, char x)

This function has a string and a character. This function requires replacing the most used character in the str with the ‘x’ character.

Note: If two characters have the same frequency, then we will have to consider the frequency which has the lower ASCII value.

Example

Input:
str: bbadbbababb
char x: t

Output:
ttadttatatt

Explanation
The maximum character repeated is ‘b’ that is replaced with ‘t’.

15. Execute the function Def Autocount(n).

The function accepts the string n. It checks whether the number is an autobiographical number or not. If an integer returns, then it is an autobiographical number. If 0 returns, then it is not an autobiographical number.

Assumption

• The input value should not be more than 10 characters.
• The input string will have numeric characters.
   

Example

Input:
N: “1210”

Output:
3

Explanation
The 0th position has the number 1, the 1st position has the number 2, the 2nd position has the number 1, and the 3rd position has number 0. Hence, it is an autobiographical number.

The count of autobiographical numbers in the input is 3, hence 3 is returned.
