终于过了这sb题了。

当初我连这道题都A不了(╯▔皿▔)╯

代码

#include <cstdio>
#include <iostream>
#define N 1000001
#define abs(x) ((x) < 0 ? -(x) : (x))

int n = 1, sum1, sum2;
char s
;

int main()
{
int i;
while(std::cin >> s
)
if(s
 == 'E') break;
else n++;
n--;
for(i = 1; i <= n; i++)
{
s[i] == 'W' ? sum1++ : sum2++;
if((sum1 >= 11 && abs(sum1 - sum2) >= 2) || (sum2 >= 11 && abs(sum1 - sum2) >= 2))
{
printf("%d:%d\n", sum1, sum2);
sum1 = sum2 = 0;
}
}
printf("%d:%d\n", sum1, sum2);
sum1 = sum2 = 0;
puts("");
for(i = 1; i <= n; i++)
{
s[i] == 'W' ? sum1++ : sum2++;
if((sum1 >= 21 && abs(sum1 - sum2) >= 2) || (sum2 >= 21 && abs(sum1 - sum2) >= 2))
{
printf("%d:%d\n", sum1, sum2);
sum1 = sum2 = 0;
}
}
printf("%d:%d\n", sum1, sum2);
return 0;
}
