Give a recursive definition for the set POWERS-OF-TWO = {1 2 4 8 16 ....} and use your definition to prove that the product of two POWERS-OF-TWO is also a POWER-OF-TWO
Determine a recurrence relation for the divide-and-conquer sum-computation algorithm. The problem is computing the sum of n numbers. This algorithm divides the problem into two instances of the same problem: to compute the sum of the first ⌊n/2⌋ numbers and compute the sum of the remaining ⌊n/2⌋ numbers. Once each of these two sums is computed by applying the same method recursively, we can add their values to get the sum in question
Find a recursive definition for the sequence 5, 7, 10, 14, 19,... for n>1.
How do I find the equation/recursive definition for this?
