You are given a string of size ‘N’ consisting of only characters ‘a’,’c’,’g’ and ’t’. You have to find all the sub-strings of the given string of length 10 that is occurring more than once in the given string.

You are given an array consisting of 'N' positive integers where each integer is either 0 or 1 or 2. Your task is to sort the given array in non-decreasing order.

Note :

1. The array consists of only 3 distinct integers 0, 1, 2.
2. The array is non-empty.

The questions were mostly HR based , asked about my projects , CS fundamentals, DSA basics , questions from CV, about company and around these topics only.

You are given an integer ‘N’. You have to print the value of Factorial of ‘N’. The Factorial of a number ‘N’ is defined as the product of all numbers from 1 to ‘N’.

For Example:

Consider if ‘N’ = 4, the Factorial of 4 will be the product of all numbers from 1 to 4, which is 1 * 2 * 3 * 4 = 24. Hence, the answer is 24.
