It is a well known fact that a number is divisible by 11 if and only if the alternating sum of its digits is equal to 0 modulo 11. For example, 8174958 is a multiple of 11, since 8 - 1 + 7 - 4 + 9 - 5 + 8 = 22.
Given a number that consists of digits from 1-9, can you rearrange the digits to create a number that is divisible by 11?
Since the number might be quite large, you are given integers A1, A2, ..., A9. There are Ai digits i in the number, for all i.
The first line of the input gives the number of test cases, T. T lines follow. Each line contains the nine integers A1, A2, ..., A9.
For each test case, output one line containing Case #x: y, where x is the test case number (starting from 1) and y is YES if the digits can be rearranged to create a multiple of 11, and NO otherwise.
336, which can be rearranged to 363. This is a multiple of 11 since 3 - 6 + 3 = 0.999999999999, which is already a multiple of 11, since 9 - 9 + 9 - 9 + ... - 9 = 0.5578, which cannot be rearranged to form a multiple of 11.111234, which can be rearranged to 142131. This is a multiple of 11 since 1 - 4 + 2 - 1 + 3 - 1 = 0.11177799, which can be rearranged to 19191777. This is a multiple of 11 since 1 - 9 + 1 - 9 + 1 - 7 + 7 - 7 = -22 (which is 0 modulo 11).8, which cannot be rearranged to form a multiple of 11.
