Chance is an esoteric programming language made in 2016 by m654 with the goal of being as hard as possible to write programs in. Chance is heavily based on chance. In fact, there is a 14% chance that a cat program written in Chance will work.

Commands in chance are grouped into 4 groups: navigation, addition/subtraction, output and input. Each command in a group has a one in three percent chance of running correctly. If it does run correctly, there is a 1 in 2 chance that it will do what you want. For example, the + command has a 1 in 3 chance of running, and on top of that, there is a 1 in 2 chance of it either adding one to the selected cell's value, or subtracting one.

## Instructions

This program has a 14% chance of running.

##### Cat variations
