zigzagConvert

Language/Type: Java string parameters return
Related Links:

Write a method named zigzagConvert that accepts a string and an integer representing a number of rows as parameters and returns a new string as follows. Think of the string's characters being displayed in columns into a "zigzag" pattern based on the given number of rows. For example, the call of zigzagConvert("ABCDEFGHIJKLMNOPQRS", 5) would think of the characters of the string as being placed into a pattern as follows: 

         column
row 1 2 3 4 5 6 7 8 9 
 1  A       I       Q
 2  B     H J     P R
 3  C   G   K   O   S
 4  D F     L N
 5  E       M

Your function should reorder the letters to be read left-to-right in row-major order. Row 1 in our example contains "AIQ", then row 2 contains "BHJPR", and so on. So this call would return "AIQBHJPRCGKOSDFLNEM". If the number of rows is 0 or less, return an empty string.

Method: Write a Java method as described, not a complete program or class.
