Self Permutation

Problem Description

You are given two strings A and B. Check whether there exists any permutation of both A and B such that they are equal.

Return a single integer 1 if its exists, 0 otherwise.

Problem Constraints
1 <= |A|, |B| <= 105
Both strings contain only lowercase english alphabets.

Input Format
The first argument is the string A. The second argument is the string B.

Output Format
Return a single integer 1 if a permutation exists, 0 otherwise.

Example Input
Input 1:

A = 'scaler'
B = 'relasc'

Input 2:

A = 'scaler'
B = 'interviewbit'

Example Output
Output 1:

1

Output 2:

0

Example Explanation
Explanation 1:

We can rearrange the second string to 'scaler', hence, a permuation exists.

Explanation 2:

The given length of the two strings itself is different. There is no possible permutation.

NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
