Problem 6: Zig Zag Conversion

Difficulty: Medium

Problem

Convert a string into zigzag pattern. See example below.

Example

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 text, int nRows);

convert("PAYPALISHIRING", 3) should return "PAHNAPLSIIGYIR".
