比如a[]={2,4,5,6,7},得出的两组数{2,4,6}和{5,7},abs(sum(a1)-sum(a2))=0: 比如{2,5,6,10},abs(sum(2,10)-sum(5,6))=1,所以得出的两组数分别为{2,10}和{5,6}. vector<int> vct; int last = INT_MAX; int halfOfSum(int* arr, int len) { int sum = 0; for (int i = 0; i < len; ++i) { sum
Value of '0' is not valid for 'emSize','emSize' should be greater than 0 and less than or equal to System.Single.MaxValue.Parameter name:emSize. 检查字体大小是不是小于等于0了. new System.Drawing.Font(name,size,fontStyle).
