Given an array ‘arr’ of size ‘n’ find the largest element in the array.


Example:

Input: 'n' = 5, 'arr' = [1, 2, 3, 4, 5]

Output: 5

Explanation: From the array {1, 2, 3, 4, 5}, the largest element is 5.
Problem approach

I sorted the array in ascending order, hence the largest element will be at the last index of the array. 

approach I used;-
Step1 - Sort the array in ascending order.
Step2 - Print the (size of the array -1)th index.

You are given a positive integer ‘N’. Your task is to print all prime numbers less than or equal to N.

Note: A prime number is a natural number that is divisible only by 1 and itself. Example - 2, 3, 17, etc.

You can assume that the value of N will always be greater than 1. So, the answer will always exist.

Problem approach

For finding Prime numbers b/w a and b i used iteration method by iterating through every number from a and b and checking for the number whether it is a prime number or not.

1. Reverse String

Moderate

Livekeeping (An IndiaMART Company)IBMMcAfee

You are given a string ‘S’. You are also given ‘M’ integers in an array ‘A’. You perform ‘M’ operations on this string. The operations are given in an array ‘A’ of size ‘M’.

You perform the operations in the order they appear in the array ‘A’. In the ‘i’th operation, you reverse the substring of ‘S’ from the position ‘A[i]’ to ‘len(S)’ - ‘A[i]’ - 1 (0 based).

Your task is to find the string after performing all the operations.

Example :
‘S’ = “aabcd”, ‘M’ = 2, ‘A’ = [0, 1]
After 1st operation i.e, reversing from [0, 4], ‘S’ = “dcbaa”.
After 2nd operation i.e, reversing from [1, 3], ‘S’ = “dabca”.
Hence, the answer is “dabca”.
Problem approach

1. Take an empty stack
2. Iterate over the given string from start to end.
3. In each iteration, push the character at index i to the stack.
4. After the first loop is completed, set a while loop till the stack is non-empty.
5. Pop the character at the stack and start re-assigning the string.
