从1到33其中6个数相加的85或86的有几组

推荐回答

#include <stdio.h> int main(void) { long i[6]; long n = 0; for (i[0] = 1; i[0] <= 14; i[0]++) for (i[1] = i[0] + 1; i[1] <= 15; i[1]++) for (i[2] = i[1] + 1; i[2] <= 19; i[2]++) for (i[3] = i[2] + 1; i[3] <= 31; i[3]++) for (i[4] = i[3] + 1; i[4] <= 32; i[4]++) for (i[5] = i[4] + 1; i[5] <= 33; i[5]++) { if (i[0] + i[1] + i[2] + i[3] + i[4] + i[5] == 85 || i[0] + i[1] + i[2] + i[3] + i[4] + i[5] == 86) { n++; } } printf("\n%ld", n); } 30680
