    6 - Zigzag Conversion\.

    Medium

    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: "PAHNAPLSIIGYIR"

    Write the code that will take a string and make this conversion given a number of rows:

    string convert(string s, int numRows);

    Example 1:

    Input: s = "PAYPALISHIRING", numRows = 3

    Output: "PAHNAPLSIIGYIR"

    Example 2:

    Input: s = "PAYPALISHIRING", numRows = 4

    Output: "PINALSIGYAHRPI"

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

    Example 3:

    Input: s = "A", numRows = 1

    Output: "A"

    Constraints:

    • 1 <= s.length <= 1000

    • s consists of English letters (lower-case and upper-case), ',' and '.'.

    • 1 <= numRows <= 1000
