- Create a program to print nested squares
- Input: Accept the width of the largest square
- Output: A series of nested squares with 1 space between them
- Sample:
- > eca4.exe 10

* Top Lines of inside squares would be 1-8 , 1-3 - 6-8 (Don't count first and last lines of largest square)
* Bottom Lines of inside squares would be 2-7, 2-4 5-7 (Don't count first and last lines of largest square)
Here is what I got so far. Please help me with some ideas to develop
