需求:将所给的字符串以“倒N型”输出,可以指定输出的行数函数 String convert(String s, int numRows)例如输入“abcdefghijklnmopqrstuvwxyz”,输出成3行:得到a e i n q u y bdfhjlmprtvxz c g k o s w 下面是一个5行的例子String s = "abcdefghijklnmopqrstuvwxyzabcdefghijklnmopqrstuvwxyzabcdefghijklnmopqrstuvwxyz&…

题意:将字符串排成Z字形. PAHNAPLSIIGYIR 如果是5的话,是这样排的 P     I AP   YR H L G N  SI A    I 于是,少年少女们,自己去找规律吧 提示:每个Z字形的字符串和原字符串的每个字母的位子一一映射 class Solution { public: string convert(string s, int numRows) { string t = s; ) return t; ; ; i < s.size(); i += * numRows -…

The string "PAYPALISHIRING" is written in a zigzag pattern on a given number of rows like this: (you may want to display this pattern in a fixed font for better legibility) P A H N A P L S I I G Y I R And then read line by line: "PAHNAPLSII…

ZigZag Conversion 看了三遍题目才懂,都有点怀疑自己是不是够聪明... 就是排成这个样子啦,然后从左往右逐行读取返回. 这题看起来很简单,做起来,应该也很简单. 通过位置计算行数: P I N A L S I G Y A H R P I 0,0 1,1 2,2 3,3 4,2 5,1 6,0 (期望) 用简单的先思考: P A H N A P L S I I G Y I R 0,0 1,1 2,2 3,3 4,0 %4 (3+1)可以解决正常的 3,1(期望) 特殊的3(2行2排…
