Five months is too long for a problem like [tag:mario] or pretty much any other problem in the course.

You could try solving it manually with low-tech tools (e.g., a pencil and a paper) trying to draw half a pyramid row-by-row from top to bottom and left to right.

Suppose the input is 5, we should get the following output...

        ##
       ###
      ####
     #####
    ######

By analyzing the problem, we can get information like:

 1. The initial number of spaces to be printed out in terms of the height (i.e., 5) is 
 
        height + 1 - the initial number of hashes
 
2. The initial number of hashes is 2.
 3. The number of spaces decreases each row until it becomes 0 in the last row.
 4. The number of hashes increases by 1 until it becomes `height + 1` in the last row.

Using this information, we could write the following pseudocode (assuming `height` is a valid integer inputted by the user):

    calculate the initial number of spaces in terms of height
    calculate the initial number of hashes in terms of height
    
    // draw the rows
    for (i = 0 to i < height, increment i)
        // draw spaces
        for (j = 0 to j < spaces, increment j)
            print a space

        // draw hashes
        for (j = 0 to j < hashes, increment j)
            print a hash
        
        move to the next row
        decrement the number of spaces
        increment the number of hashes
