Problem:
 Score : 200 points    Problem Statement 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.      Constraints  1 \leq |w| \leq 100  w consists of lowercase letters ( a - z ).         Input The input is given from Standard Input in the following format:  w       Output Print Yes if w is beautiful. Print No otherwise.        Sample Input 1 abaccaba      Sample Output 1 Yes  a occurs four times, b occurs twice, c occurs twice and the other letters occur zero times.       Sample Input 2 hthth      Sample Output 2 No
