求助，代码样例过了，全WA，救救孩子

#include<stdio.h>
int main() {
	char c;
	int a[40020] = { 0 };
	int i = 1, flag;
	for (; scanf("%c", &c) && c > 47 && c < 50;)
		i += !(i & 1 ^ (c - '0')), a[i]++, a[0]++;
	for (int j = 1; j < a[0]; j++) {
		for (; scanf("%c", &c) && c > 47 && c < 50;)
			i += !(i & 1 ^ (c - '0')), a[i]++;
	}
	flag = i;
	for (int i = 0; i <= flag; i++) {
		printf("%d ", a[i]);
	}
	return 0;
