Invitation to CodeChef March Lunchtime 2020

I invite you to experience 3 hours of uninterrupted coding experience at the March Lunchtime. This 3-hour contest will offer 5 challenging problems to solve. A showdown to reach the top spot. So sharpen your coding skills and get ready to pack your Lunchtime with a box of Code. And not forgetting about our Birthday Surprise, you stand to win Laddus, with double the chances.

The problem statements of the contest will be available in English, Hindi, Bengali, Russian, Mandarin, and Vietnamese. Also, if you have some original and engaging problem ideas, and you’re interested in them being used in the CodeChef’s contests, you can share them here: Problem Idea Submission | CodeChef.
