XO: Equal Counts of X and O

You are given a string s. Your task is to check whether the number of occurrences of the letter x is equal to the number of occurrences of the letter o in the string.

Note that the comparison should be case-insensitive. In other words, uppercase and lowercase letters are considered the same. Formally, let \(X = \text{count}(\text{'x'})\) and \(O = \text{count}(\text{'o'})\). The answer is True if \(X = O\) and False otherwise.

If the string does not contain either x or o, then \(X = 0\) and \(O = 0\) are trivially equal, so the output should be True.

inputFormat

The input consists of a single line containing a string s. The string can contain any ASCII characters.

outputFormat

Output a single line containing either True or False depending on whether the number of 'x' and 'o' characters in s (ignoring case) are equal.
