#include <stdio.h> #include <conio.h> #include <stdlib.h> //system(); 这个指令需要用到此头文件 #include <ctype.h> //toupper要用到 #include <malloc.h> //在内存管理时用到的头文件 #include <string.h> //字符串的头文件 #include <math.h> //数学运算 int m = 0, n = 0, c[1000] = { NULL }, position = 0, count_can = 0; bool jump(int x[]) { int temp1[1000] = { NULL }, temp2[1000] = { NULL }; for (int i = 0; x[i] != NULL; i++) { if (x[i] == 1) return(true); temp1[i] = x[i]; } int l = 1, s = 0; do{ s = 0; if (l == 1) { for (int i = 0; temp1[i] != NULL; i++) { for (int j = i + 1; temp1[j] != NULL; j++) { if (fabs(temp1[i] - temp1[j]) == 1) { return(true); } if (temp1[i] - temp1[j] != 0) { temp2[s] = (int)fabs(temp1[i] - temp1[j]); s++; } } temp1[i] = 0; } l = 2; } else { for (int i = 0; temp2[i] != NULL; i++) { for (int j = i + 1; temp2[j] != NULL; j++) { if (fabs(temp2[i] - temp2[j]) == 1) { return(true); } if (temp2[i] - temp2[j] != 0) { temp1[s] = (int)fabs(temp2[i] - temp2[j]); s++; } } temp2[i] = 0; } l = 1; } } while (s != 0); return(false); } void card(int depth) { if (depth == m) { c[m] = n; if (jump(c) == true) { count_can++; } return; } else { for (int i = 1; i <= n; i++) { c[depth] = i; depth++; card(depth); depth--; } return; } } void main() { scanf("%d%d", &m, &n); card(0); printf("%d\n", count_can); }
