Keyboard Madness Runner

Simple program exercise given to me by an ex coworker sometime ago for fun. This is a Rust port of my program that was written F#.

Exercise details

"1" "2" "3" "4" "5" "6" "7" "8" "9" "0"
"Q" "W" "E" "R" "T" "Y" "U" "I" "O" "P"
"A" "S" "D" "F" "G" "H" "J" "K" "L" ";"
"Z" "X" "C" "V" "B" "N" "M" "," "." "?"

Given this keyboard layout, an starting point of (4, 2) "G" and string of instructions, print out any selected keys. Instructions are separated by a comma, with some instructions haveing a count with them, meaning to repeat to give an action by the number of count.

Instructions

• "R" - Move Right, can also have a count like "R:3"
• "L" - Move Left, can also have a count like "L:3"
• "D" - Move Down, can also have a count like "D:2"
• "U" - Move Up, can also have a count like "U:2"
• "_" - Add a space to the selected keys
• "N" - Add a new line to the selected keys
• "S" - Select the key at that point

Any unknown instructions are ignored

Sample instruction looks like R,S,U,L:3,S,D,R:6,S,S,U,S which will output "HELLO"

Running Unit Test

Run cargo test

Run Command line Application

Run cargo run R,S,U,L:3,S,D,R:6,S,S,U,S
