1. Minimum Swaps To Make Two Strings Equal

Asked in companies
You are given two strings, ‘s1’ and ‘s2’, each of length ‘N’. The strings ‘s1’ and ‘s2’ are anagrams (i.e., they contain the same characters). You can swap the position of any two characters in ‘s1’ any number of times. The task is to find the minimum number of swaps we need to perform to make ‘s1’ equal to ‘s2’.
Example :
s1 = “bac”, s2 = “acb”, n = 3
We need to perform at least two swaps to make ‘s1 = s2’:
1. Swap ‘b’ and ‘a’, so:
s1 = “abc”
2. Swap ‘b’ and ‘c’, so:
s1 = “acb”
So, the answer is ‘2’.
