输入
The first line of the inputcontains one integer T, which is the number of test cases (1<=T<=10). Each test casespecifies:
* Line 1: N ( 1 ≤ N ≤ 100 )
* Line 2: X1 X2… Xn ( 1 <= Xi<=1000 i=1…. n)

大意是有n个东西，可以全部破坏或者只破坏一部分，最后破坏的人获胜。
#include
#define N 120
int a[N];
int main()
{
int sum,n,t,i;
scanf("%d",&t);
while(t--)
{
scanf("%d",&n);
for(i=0;i 有一道相同的题是给出n堆石子，每次可以从一堆中取出部分石子或者全部取完，谁取完最后一个石子获胜。一样的道理。
