Given a number, return the bingo letter associated with it (capitalized). Bingo numbers are grouped as follows:

LetterNumber Range
"B"1-15
"I"16-30
"N"31-45
"G"46-60
"O"61-75

--hints--

getBingoLetter(75) should return "O".

js
assert.equal(getBingoLetter(75), "O");

getBingoLetter(54) should return "G".

js
assert.equal(getBingoLetter(54), "G");

getBingoLetter(25) should return "I".

js
assert.equal(getBingoLetter(25), "I");

getBingoLetter(38) should return "N".

js
assert.equal(getBingoLetter(38), "N");

getBingoLetter(11) should return "B".

js
assert.equal(getBingoLetter(11), "B");
