Description

Difficulty: medium

NumRows a given string s according to the given number of lines, Z-shaped from top to bottom and from left to right.

For example, if the input string is "PAYPALISHIRING" and the number of lines is 3, the arrangement is as follows:

P A H N A P L S I I G Y I R

After that, your output needs to be read line by line from left to right to produce a new string, such as "PAHNAPLSIIGYIR".

Please implement this function that converts a string to a specified number of lines:

String convert (string s, int numRows)

Example 1:

Input: s = "PAYPALISHIRING", numRows = 3 output: "PAHNAPLSIIGYIR"

Example 2:

Input: s = "PAYPALISHIRING", numRows = 4 output: "PINALSIGYAHRPI"

P I N A L S I G Y A H R P I

Example 3:

Input: s = "A", numRows = 1 output: "A"
