Tally with an Associative Array

Bash & Scripting · pro · solved in-browser (no VM needed) · 3 tiered hints

Write /home/player/tally.sh (shebang #!/bin/bash) that counts occurrences of words read from stdin using an associative array. Declare it with `declare -A`, increment a keyed counter with (( arr[key]++ )), and finally iterate the keys with ${!arr[@]} to print each word and its count. (Authored config, graded structurally — the engine isn't run here.)
