( 24381 ) A Boboniu Likes to Color Balls PROGRAMMING brute force 1000

B'Boboniu gives you He allows you to do the following operation as many times as you want: You should answer if it 's possible to arrange all the balls into a palindrome after several (possibly zero) number of described operations. The first line contains one integer T ( 1 <= T <= 100 ) denoting the number of test cases. For each of the next T cases, the first line contains four integers r , g , b and w ( 0 <= r,g,b,w <= 10^9 ). For each test case, print "Yes" if it 's possible to arrange all the balls into a palindrome after doing several (possibly zero) number of described operations. Otherwise, print "No". In the first test case, you 're not able to do any operation and you can never arrange three balls of distinct colors into a palindrome. In the second test case, after doing one operation, changing (8,1,9,3) to (7,0,8,6) , one of those possible palindromes may be "rrrwwwbbbbrbbbbwwwrrr". A palindrome is a word, phrase, or sequence that reads the same backwards as forwards. For example, "rggbwbggr", "b", "gg" are palindromes while "rgbb", "gbbgr" are not. Notice that an empty word, phrase, or sequence is palindrome. '...
