great video. amazing detail in the demonstration

Super good explanation! Thanks for your help

Is it not simpler to use logarithms? Logarithms convert addtion to multiplication, so we don't need the + symbol...

there is a loop present, so how its become constant time complexity? can u please clarify my doubt?

I would prefer you wrote the explanation while writing the code because you did not show what happens when there is a carry i.e. when it does not equal 0 in the previous explanation. The while loop condition says while carry is not 0 so now I am confused if the carry is a single digit. Edit: In fact, I found from chatgpt that 6 + 6 does have a carry but you reversed the operations so that confused me.
