Largest Product in a Grid — Project Euler (Problem 11)

I started solving Project Euler problems this month. Check out the Project Euler tab of this blog for a list of the problems I’ve solved (with solutions) till date. Here’s a problem you might find interesting:


Here’s my solution using Python (I basically search through the entire matrix which is of O() complexity):

I first copy the maxtrix into a text file euler11.txt so that it can be later read into Python

I then execute the following code from the same working directory as euler11.txt

One thought on “Largest Product in a Grid — Project Euler (Problem 11)

  1. This is a little bit late, but I just found this and think the loop sequence is very clean, but I was wondering why you wouldn’t substitute all your top lines for this:
    problemMatrix = np.loadtxt(“euler11.txt”)

    Is there some benefit to your method?
    Really like the blog btw
