Hi Mr. Gillespey, In the even or odd subsets thing, can u just divide the number of subsets by two, instead of doing 2^(n-1)
Yes you can do it that way. But why multiply then divide its just more work.
An easier way to find the amount of subsets is to multiply 2^# of elements
Oops you said that in the video. I posted this before you said that.
That is true but do you know why it works?
Its actually really cool.
