There is a round safe lock with the numbers 0-99. I have a text file called "inputs.txt" that has a bunch of instructions separated by line terminators. The instructions are like "L38" or "R15" and tell you turn the safe lock left or right by the given number. The safe lock starts at 50, I need to find how many times the safe lock hits the number 0.

let bound = 100, t = 50, hits = 0;
Deno.readTextFileSync("input.txt").split("\r\n").map(s => s.replace("L", "-").replace("R", "")).forEach(n => {
  if ((t +=+ n) < 0 ? t = -(-t % bound) : t %= bound); else ++hits;
});
console.log("password:", hits);
