题目大意:给出一个文本,问说有多少种理解方式。
1. $$中间的,(s1+1) * (s2+1) * ...*(sn+1), si表示连续的空格数。
2.{}中间,即 | 的个数+1.
解题思路:模拟。
#include <cstdio>
#include <cstring>
#include <algorithm>
using namespace std;
const int maxn = 1<<22;
typedef long long ll;
int n, len;
char str[maxn], ch;
bool solve () {
ll ans = 1, tmp = 1e5;
for (int i = 0; i < len; i++) {
ll cnt = 1;
if (str[i] == ‘$‘) {
int j;
for (j = i+1; str[j] != ‘$‘;) {
ll k = 0;
while (str[j++] == ‘ ‘)
k++;
if (k)
j--;
if ((k+1) > tmp / cnt)
return true;
/*
*/
cnt *= (k+1);
if (cnt > tmp)
return true;
}
i = j;
} else if (str[i] == ‘{‘) {
i++;
while (str[i] != ‘}‘) {
if (str[i++] == ‘|‘)
cnt++;
}
if (cnt > tmp)
return true;
}
ans *= cnt;
tmp = 1e5 / ans;
}
if (ans > 1e5)
return true;
printf("%d\n", (int)ans);

}

for (int i = 0; i < n; i++) {
gets(str+len);
len += strlen(str+len);
}
if (solve())
printf("doge\n");
}
return 0;
