大一萌新，求大佬指教，只会用纯C语言，p1p2p3的处理逻辑在注释里写了。测试样例能过

#include <stdio.h>
#include <string.h>
void Cut_in(char goal[], int i, int len, int p1, int p2, int p3);
void Delete(char goal[], int i, int len);
int main()

	scanf("%d%d%d", &p1, &p2, &p3);
	getchar();
	char goal[1000]="\0";
	gets(goal);
	int len = strlen(goal);
	for (int i = 0; i < len; i++){
		if (goal[i] == '-'){
			if (goal[i + 1] - goal[i - 1] > 1) Cut_in(goal,i,len,p1,p2,p3);
			else if (goal[i + 1] - goal[i - 1] == 1) Delete(goal,i,len);

		}
	}
