HackerRank
HackerRank is a tech company that focuses on competitive programming challenges for both consumers and businesses, where developers compete by trying to program according to provided specifications. HackerRankโs programming challenges can be solved in a variety of programming languages (including Java, C++, PHP, Python, SQL, JavaScript) and span multiple computer science domains. When a programmer submits a solution to a programming challenge, their submission is scored on the accuracy of their output. Programmers are then ranked globally on the HackerRank leaderboard and earn badges based on their accomplishments to drive competition among users.

This repository contains simple sets of codes that draw triangles in the form of ASCII art using MySQL. I cam across these codes on HackerRank and I thought it was a very strange concept to SQL to draw triangles with ASCII art. But then it became a challenging tasks and I learned to use information_schema.tables, a dummy table that exists in every MySQL session.
