Implement the Function any$($s$1,$ s$2)$

Requirements:

Write a function int any$($const char $*$s$1,$ const char $*$s$2)$ that searches the string s$1$ for the

first occurrence of any character present in the string s$2.$

The function should return the zero$-$based index of the first character in s$1$ that matches any

character in s$2.$

If no characters from s$2$ are found in s$1,$ the function should return $-1.$
