生成随机样例:
eg:
代码:
#include<iostream> #include<cstdio> #include<algorithm> #include<cstring> #include<cstdlib> int Rand(int x, int o) { //if o set, return [1, x], else return [0, x - 1] if (!x) return 0; int tem = (int)((double)rand() / RAND_MAX * x) % x; return o ? tem + 1 : tem; }
void data_gen() { int kases = 10; printf("%d\n", kases); while (kases--) { int N = Rand(100, 1);//[1, 100] printf("%d\n", N); for(int i=1; i<=N; i++) { int sign = Rand(2, 0);//[0, 2) int x = Rand(10000, 0); if (sign) x = -x; printf("%d ", x); } printf("\n"); } } int main() { freopen("in.txt","w",stdout); data_gen(); }
