45 mins was for coding round, in which we have to find errors in 7 codes.
The codes where pre written based on some problem, we just have to spot errors and make the code work correctly.

In the first 2hr we have numerical ability questions, mostly based on work and time, ages and profit and loss.
25 questions based on English grammar and sentences

1. String Palindrome

Easy

0/40

Asked in companies

Given a string, determine if it is a palindrome, considering only alphanumeric characters.

Palindrome

A palindrome is a word, number, phrase, or other sequences of characters which read the same backwards and forwards.

Example:

If the input string happens to be, "malayalam" then as we see that this word can be read the same as forward and backwards, it is said to be a valid palindrome.

The expected output for this example will print, 'true'.

From that being said, you are required to return a boolean value from the function that has been asked to implement.

2. Nth Fibonacci Number

Easy

0/40

Asked in companies

The n-th term of Fibonacci series F(n), where F(n) is a function, is calculated using the following formula -

    F(n) = F(n - 1) + F(n - 2), 
    Where, F(1) = 1, F(2) = 1

Provided 'n' you have to find out the n-th Fibonacci Number. Handle edges cases like when 'n' = 1 or 'n' = 2 by using conditionals like if else and return what's expected.

"Indexing is start from 1"

Example :

Input: 6

Output: 8

Explanation: The number is ‘6’ so we have to find the “6th” Fibonacci number.
So by using the given formula of the Fibonacci series, we get the series:    
[ 1, 1, 2, 3, 5, 8, 13, 21]
So the “6th” element is “8” hence we get the output.

def Fibonacci(n):

    if n<= 0:

        print("Incorrect input")

    elif n == 1:

        return 0
    elif n == 2:

        return 1

    else:

        return Fibonacci(n-1)+Fibonacci(n-2)
print(Fibonacci(10))
