Exemple #3

insert_mult_bits(num, bits, len, i): insert multiple bits with len at specific position
For example:
Input: num = 101 (5)
insert_mult_bits(num, 7, 3, 1): 101111 (47)
insert_mult_bits(num, 7, 3, 0): 101111 (47)
insert_mult_bits(num, 7, 3, 3): 111101 (61)
"""

"""
Insert exact one bit at specific position
Algorithm:
1. Create a mask having bit from i to the most significant bit, and append the new bit at 0 position
2. Keep the bit from 0 position to i position ( like 000...001111)
3. Merge mask and num
