Did you go to the peak?

Hi Larry, Just curious, how you decide wether is left < right or left

[@Algorithmist]

I talk about this in the video! (The part about inclusive bounds)

[@narolavarshil6067]

how are you able to figure out (left+right+1)//2 as mid and not (left+right)//2

[@Algorithmist]

When you do mid - 1 on something you need it to round up on odd

[@JustBR0]

return arr.index(max(arr)) It works!!

As long as you're learning something new!
