A man fell in a 50m deep well. He climbs 4 meters up and slips 3 meters down in one day. How many days would it take for him to come out of the well?

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.

You are provided with the two strings named X and Y respectively. Y has its own specific order and has no repeating characters. Your task is to arrange the characters of the first string i.e. X in such a way that the order of characters in X is exactly the same as in Y, which means if ‘d’ occurs after ‘c’ in Y then it should also occur after ‘c’ in X ( obviously if X has ‘d’ and ‘c’ as characters in it ). All you have to do is, convert string X in the specific order with respect to string Y.

Note :

Both the strings have only lowercase English alphabets. 
There may be more than one correct solution, you have to return any one of the possible solutions.
