You have N rectangles. A rectangle is golden if the ratio of its sides is in between [1.6,1.7], both inclusive. Your task is to find the number of golden rectangles.
- First line: Integer N denoting the number of rectangles
- Each of the N following lines: Two integers W, H denoting the width and height of a rectangle
- Print the answer in a single line.
5 10 1 165 100 180 100 170 100 160 100
There are three golden rectangles: (165, 100), (170, 100), (160, 100).
Solution in Python
n = int(input()) a = [list(map(int,input().split())) for i in range(n)] print(sum(1 for i in a if max(i)/min(i)>=1.6 and max(i)/min(i)<=1.7))
We use max(i)/min(i) so that always the long the longer side gets divided by the smaller side. That is, either (100,120) or (120,100) our division will be 120/100.
