1. Which of the following statements are correct? (Select all that applies.) Group of answer choices a. Merge-sort and quick-sort algorithms are based on the divide-and-conquer paradigm. b. The time complexity of selection-sort algorithm is O(n^2). c. The time complexity of insertion-sort algorithm is O(n^2). d. The time complexity of heap-sort and merge sort algorithms is O(nlogn). e. running time of quick-sort algorithm is O(nlogn). 2. The key process in quick-sort is the partition. The target of partitions is, given an array and an element x of an array as the pivot, put x at its correct position in a sorted array and put all smaller elements (smaller than x) before x, and put all greater elements (greater than x) after x. Group of answer choices a. True b. False
