  /*
  Function for converting Binary to Hex

  1. The conversion will start from Least Significant Digit (LSB) to the Most Significant Bit (MSB).
  2. We divide the bits into sections of 4-bits starting from LSB to MSB.
  3. If the MSB get less than 4 bits, then we pad 0s to the front of it.

  For Example:
  Binary String = '1001101'

  1. Divide it to 2 parts => ['100', '1101']
  2. Pad 0s the MSB so it'll be => ['0100', '1101']
  3. Use the lookup table and merge them, therefore the result is 4D.
