Using a nested for loop create patterns 1, 2, and 3 shown below. In function main prompt the user for the height (number of rows) and width (number of characters per line) for pattern 1. You may use any number for height and width, just as long as the basic pattern is preserved. For pattern 1, make use of an if structure to instruct the program what to print on the various lines and columns. Also use nested for loops to create patterns 2 and 3 using the same height as in pattern 1
