  1. Recurrences / Divide&Conquer HW: 2.4 Quiz: 2.1, 4.1, 4.2, 5.2, 7.3, 7.4 Midterm: 8 given a recursive algorithm, state the recurrence solve a recurrence, using Master theorem given a recurrence and its solution, prove that the solution is correct solve a problem using divide&conquer (study: merge sort, closest pair of points in R2)

  2. Basics Quiz: 1.1, 1.2, 13.1 Midterm: 7 group a bunch of function by their asymptotic growth loga b a = b c (ab ) = abc ab+c = (ab)(ac)

  3. Basics Quiz: 1.1, 1.2, 13.1 Midterm: 7 quicksort, heapsort, mergesort, counting sort, bucket sort, radix sort, sorting lower bound heaps, B-trees union find basic geometry (do two lines intersect, is a point to the left of a line, ...)
