Let w be a string consisting of lowercase letters. We will call w _beautiful_ if the following condition is satisfied:    * Each lowercase letter of the English alphabet occurs even number of times in w.  You are given the string w. Determine if w is beautiful.
import sys
input = sys.stdin.readline

s = input()

arr = [(s.count(num)%2==0) for num in s]

print("Yes" if all(arr) else "No")

import sys
input = sys.stdin.readline

s = input().strip()

arr = [(s.count(num)%2==0) for num in s]

print("Yes" if all(arr) else "No")
