( 21898 ) A Difference Operations PROGRAMMING greedy math

B'You are given an array a consisting of n positive integers. You are allowed to perform this operation any number of times (possibly, zero): Is it possible to make a_i=0 for all 2 <= i <= n ? The input consists of multiple test cases. The first line contains a single integer t ( 1 <= t <= 100 ) -- the number of test cases. The description of the test cases follows. The first line contains one integer n ( 2 <= n <= 100 ) -- the length of array a . The second line contains n integers a_1,a_2, ldots,a_n ( 1 <= a_i <= 10^9 ). For each test case, print "YES" (without quotes), if it is possible to change a_i to 0 for all 2 <= i <= n , and "NO" (without quotes) otherwise. You can print letters in any case (upper or lower). In the first test case, the initial array is [5,10] . You can perform 2 operations to reach the goal: In the second test case, the initial array is [1,2,3] . You can perform 4 operations to reach the goal: In the third test case, you can choose indices in the order 4 , 3 , 2 . '...
