Asked in companies

You are given an array 'ARR' of distinct positive integers. You need to find all numbers that are in the range of the elements of the array, but not in the array. The missing elements should be printed in sorted order.

Example:

If the given array is [4, 2, 9] then you should print "3 5 6 7 8". As all these elements lie in the range but not present in the array.

Problem approach

Tip 1 : The length of the array is n-1. So, the sum of all n elements i.e. sum of numbers from 1 to n can be calculated using the formula n*(n+1)/2. Now find the sum of all the elements in the array and subtract it from the sum of the first n natural numbers, it will give us the value of the missing element.

1. Check Palindrome

Easy

0/40

Asked in companies

You're given an alphabetical string ‘S’.

Determine whether it is palindrome or not. A palindrome is a string that is equal to itself upon reversing it.

For example:

‘S’ = racecar
The reverse of ‘S’ is: racecar
Since ‘S’ is equal to its reverse. So ‘S’ is a palindrome.
Hence output will be 1.

Problem approach

1. Take a string from the user.
2. Pass the string as an argument to a recursive function.
3. In the function, if the length of the string is less than 1, return True.
4. If the last letter is equal to the first letter, recursively call the function with the argument as the sliced list with the first character and last character removed else return False.
5. Use an if statement if check if the returned value is True of False and print the final result.
6. Exit.
