Give you two strings: s1 and s2. If they are opposite, return true; otherwise, return false

EXPLANATION CODE:
1) This Python method examines whether the input strings s1 and s2 are "opposite" or not. The word "opposite" is described as follows in this context:
2) Two strings are opposite if they have the same length and for each character in one string, the corresponding character in the other string is of opposite case (i.e., uppercase if the character in the first string is lowercase, and vice versa).
3) The function first checks if the length of s1 is zero. If it is, then the function returns False because an empty string cannot be opposite to any other string.
4) Next, the function iterates through each character in s1 using a for loop and checks if the corresponding character in s2 is of opposite case. This is done using the islower() method, which returns True if the character is lowercase and False if it is uppercase. If the characters in the two strings are not of opposite case, the function returns False.
5) If all characters in s1 and s2 are of opposite case, the function returns True, indicating that the two strings are opposite.
