For today's coding challenge, you'll get a matrix of single letters (kinda like in a crossword puzzle, but without any blank spaces) and a word to find. You'll need to return the start and end indices of that word. Check it out on the freeCodeCamp mobile app.

Finding the shortest path sounds simple until you have many routes, weights, and possible paths to compare.

In this video essay, @EstefaniaCassN explains how Dijkstra's Algorithm works.

You'll learn about graphs, nodes, edges, weights, greedy selection, adjacency lists, and how ortest path in Python.

So here's a course for you: Sunny teaches you Python from the ground up.

You'll install Python, write your first program, learn variables, strings, operators, conditionals, and loops, then build some co/AtTliLB9ES

You may have heard "It worked on my machine" recently and wondered "how can this still happen?"

Well, it's because local, staging, and production environments rarely stay the same, which can create production-only bugs.

In this article, @manishmshiva explains why environment neering time and what can help.
