Description

When the characters of a string are laid out in a zigzag pattern across numRows rows and then read row by row, a new string results. Implement convert(s, numRows) to perform this transformation.

Example 1:

P A H N

A P L S I I G

Y I R

Example 2:

string convert(string s, int numRows);

Example 3:

Input: s = "PAYPALISHIRING", numRows = 3

Output: "PAHNAPLSIIGYIR"

Example 4:

Input: s = "PAYPALISHIRING", numRows = 4

Output: "PINALSIGYAHRPI"

Explanation:

P I N

A L S I G

Y A H R

P I

Example 5:

Input: s = "A", numRows = 1

Output: "A"
