--hints--

getBingoRange("B") should return [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15].

assert.deepEqual(getBingoRange("B"), [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]);

getBingoRange("I") should return [16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30].

getBingoRange("N") should return [31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45].

getBingoRange("G") should return [46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60].

assert.deepEqual(getBingoRange("G"), [46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60]);

getBingoRange("O") should return [61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75].

assert.deepEqual(getBingoRange("O"), [61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75]);
