A L G O R I T H M _ T I M E

This second algorithm is a bit of a doosy, but its definitely a basis for other algorithms we will encounter.















Is it ordered?

Lets say it is this time. So how can we search this array?















First, lets come up with our own algorithm together

First Try? First Whiteboard















Another Big O trick

If the input halves at each step, its likely O(LogN) or O(NlogN)















One of the greatest algos ever!















Lets implement it

To the typescripts!

  • dont forget to divide by 2
