hello @mohitenikhil888

in the later part of the video. bahiya made it n-1.

reason
a) we are counting from 0 (i.e we are considering 0 the first fibonnaci is at 0th place)

comsider this example where we have to find 6th fibonnaci no->
a=0
b=1
then we iterate n-1 times ( n is 6 so n-1 will be 5)
1st iteration -> c will be 1
2nd iteration -> c will be 2
3rd iteration -> c will be 3
4th iteration -> c will be 5
5th iteration -> c will be 8

so thats how 6th fib is coming 8.
