const isEven = num => ((num & 1) == 0)

const isNthBit = (num, n) => (num & (1 << n))

const setNthBit = (num, n) => (num | (1 << n))

const unsetNthBit = (num, n) => (num & ~(1 << n))

const toggleNthBit = (num, n) => (num ^ (1 << n))

const findRightmost1Bit = num => (num & (-num))

const unsetRightmost1Bit = num => (num & (num - 1))

const asBitArrayString = num => num.toString(2)

const asBitArrayNumber = str => parseInt(str, 2)
