Build a pyramid

Your program is required to read a single line of input from the user (without printing any input prompt), which is expected to be a positive integer n. You can freely assume this will be a positive integer, and it's not important what you do in any other case; we'll only test your program with positive integer input. You can also freely assume that n will not be greater than 999. After reading the input, your program will print a block pyramid of size n. The bottom level of the pyramid will be n blocks wide, the level just above that will be n − 1 blocks wide, and so on, with the top level consisting of a single block. Each level's blocks are centered with respect to the blocks on the level below. The precise format is best demonstrated with an example. If the input to the program was 3, the output would look like this: See attached image. A few additional requirements apply: - Though I've indented the text above to set it apart from the rest of this project write-up, note that the bottom level of blocks must begin in the leftmost column of the output (i.e., it should not be indented). - There must be no spaces after the last * character on each line. - There must be a newline character on the end of each line, including the last one.
