A number can be called v-number if the sum of the lower half of the array is equal to the sum of the upper half of the array.

EXAMPLE:

if num = 1221

sum of lower half = 3

sum of upper half = 3

then it can be called as v-number

INPUT: First line consists of number of test cases T. Next T lines consists of a number N.

OUTPUT: For every number N print "YES"(without quotes) if the number is V-number else "NO"(without quotes)
