水题。由于没注意空格错了一会。
题意就是告诉第i个右括号前有几个左括号
打印第i个括号,前有几个匹配的括号
思路用的:STL队列,逆匹配
#include <iostream> #include <cstdio> #include <cstring> #include <cstdlib> #include <algorithm> #include <queue> using namespace std; char s[1000]; int main() { std::ios::sync_with_stdio(false); int t,n,i,j,a[30],b[30],l; cin>>t; while(t--) { cin>>n; l = 0; for(i = 0;i<n;i++) { cin>>a[i]; b[i] = a[i] + i; } for( i = 0;i<a[0];i++) s[i] = ‘(‘; s[i] = ‘)‘; l = i; l++; for(i = 1;i<n;i++) { for(j = 0;j<a[i]-a[i-1];j++) s[l++] = ‘(‘; s[l++] = ‘)‘; } s[l] = ‘\0‘; queue<char>q; int co = 0; for(i = 0;i<n;i++) { q.push(s[b[i]]); co = 0; for(j = b[i]-1;j>=0;j--) { if(q.empty()) break; if(s[j]==‘)‘) q.push(s[j]); else if(s[j]==‘(‘ && q.front()==‘)‘) { q.pop(); co++; } } if(i<n-1) printf("%d ",co); else printf("%d\n",co); } } return 0; }
