Video Summary :
Approach 1 (Reverse + Math.pow):
Reverse the linked list so that the lowest significant bit comes first. Then, iterate from right to left, adding 2^power whenever there's a 1.
Approach 2 (Bit Shifting):
Traverse once from left to right, shifting previous value left by one (equivalent to multiplying by 2) and appending each node's bit using bitwise OR. It's concise and efficient, avoiding reversal and Math functions.
