# Problem Statement
# For a given two strings, 'str1' and 'str2', check whether they are a permutation of each other or not.

# Permutations of each other
# Two strings are said to be a permutation of each other when either of the string's characters can be rearranged so that it becomes identical to the other one.
# Example:
#   str1 = 'sinrtg'
#   str2 = 'string'
# The character of the first string(str1) can be rearranged to form str2 and hence we can say that the given strings are a permutation of each other.
