# 3 x 3 grid, has 1 3*3, 4 2*2, 9 1*1 | |
# the easy way to calculate this is to subtract the number you need from the width | |
# so 2 x 2 in a 3 x 3 grid would be (3 -(2-1)) * (3 -(2-1)) = 4 | |
gridSize = 9 | |
total = 0 | |
# first we start with the smallest square and go up to the widest square | |
for x in range(1,gridSize+1): | |
if x ==1: | |
total = total + (gridSize * gridSize) | |
else: | |
total = total + (gridSize - (x-1)) * (gridSize - (x-1)) | |
print total |
