ones_and_zeros.ts

// Given an array of ones and zeroes, convert the equivalent binary value to an integer.
//     Eg: [0, 0, 0, 1] is treated as 0001 which is the binary representation of 1.
// Examples:

// Testing: [0, 0, 0, 1] ==> 1
// Testing: [0, 0, 1, 0] ==> 2
// Testing: [0, 1, 0, 1] ==> 5
// Testing: [1, 0, 0, 1] ==> 9
// Testing: [0, 0, 1, 0] ==> 2
// Testing: [0, 1, 1, 0] ==> 6
// Testing: [1, 1, 1, 1] ==> 15
// Testing: [1, 0, 1, 1] ==> 11
// However, the arrays can have varying lengths, not just limited to 4.
