题目地址:http://poj.org/problem?id=1068 /* 题意:给出每个右括号前的左括号总数(P序列),输出每对括号里的(包括自身)右括号总数(W序列) 模拟题:无算法,s数组把左括号记为-1,右括号记为1,然后对于每个右括号,numl记录之前的左括号 numr记录之前的右括号,sum累加s[i]的值,当sum == 0,并且s[i]是左括号(一对括号)结束,记录b[]记录numl的值即为答案 我当时题目没读懂,浪费很长时间.另外,可以用vector存储括号,还原字符串本来的…

Parencodings 题意: 由括号序列S可经P规则和W规则变形为P序列和W序列. p规则是:pi是第i个右括号左边的左括号的数: w规则是:wi是第i右括号与它匹配的左括号之间右括号的数(其中包括它本身). 题解: 这题真的好简单,数据也小,算是一个增加了我信心的题吧. 1是左括号,2是右括号. 代码: #include <vector> #include <cstdio> #include <string> #include <cstdlib> #i…
