--description--

Given a string, return "digits" if the string has more digits than letters, "letters" if it has more letters than digits, and "tie" if it has the same amount of digits and letters.

  • Digits consist of 0-9.
  • Letters consist of a-z in upper or lower case.
  • Ignore any other characters.

--hints--

digitsOrLetters("abc123") should return "tie".

js
assert.equal(digitsOrLetters("abc123"), "tie");

digitsOrLetters("a1b2c3d") should return "letters".

js
assert.equal(digitsOrLetters("a1b2c3d"), "letters");

digitsOrLetters("1a2b3c4") should return "digits".

js
assert.equal(digitsOrLetters("1a2b3c4"), "digits");

digitsOrLetters("abc123!@#DEF") should return "letters".

js
assert.equal(digitsOrLetters("abc123!@#DEF"), "letters");

digitsOrLetters("H3110 W0R1D") should return "digits".

js
assert.equal(digitsOrLetters("H3110 W0R1D"), "digits");

digitsOrLetters("P455W0RD") should return "tie".

js
assert.equal(digitsOrLetters("P455W0RD"), "tie");

--seed--

--seed-contents--

js
function digitsOrLetters(str) {

  return str;
}

--solutions--

js
function digitsOrLetters(str) {
  let digitCount = 0;
  let letterCount = 0;

  for (let char of str) {
    if (/[0-9]/.test(char)) digitCount++;
    else if (/[a-zA-Z]/.test(char)) letterCount++;
  }

  if (digitCount > letterCount) return "digits";
  if (letterCount > digitCount) return "letters";
  return "tie";
}
