Replace even | Function to count the minimum number of substrings of str1 such that replacing even - indexed characters of those substrings converts the str1 to str2.
Stores length of str1.
Stores minimum count of operations to convert str1 to str2.
Traverse both the given string.
If current character in both the strings are equal.
Stores current index of the string.
If current character in both the strings are not equal.
Replace str1 [ ptr ] by str2 [ ptr ].
Update ptr.
Update cntOp.

#Here is code to replace even and the other steps required.

			continue
		ptr = i
		while ( ptr < N and str1 [ ptr ] != str2 [ ptr ] ) :
			str1 [ ptr ] = str2 [ ptr ]
			ptr += 2
		cntOp += 1
	return cntOp
