The following exercise assesses your ability to do the following:

Use and manipulate String objects in a programming solution.

Design a flowchart, or pseudocode, for the following program:

Write a program that reads text from a file. Create a $2-$dimensional character array that is rows $*$ columns. Fill the array as follows:

$-$ On even numbered rows, fill the row from the leftmost column to the rightmost.

$-$ On odd numbered rows, fill the row from the rightmost column to the leftmost.

$-$ Fill any unused spaces in the $2$D array with the $*$ character. If you have more characters than space, ignore the excess characters.

Extract the characters from your array in column$-$major order $($pull from column $0$ first, then column $1,$ etc.$).$ Build a new string as you extract the characters. Display the new string.
