Sample text

Classify these mathematical functions according to their O(): (a) 13n (b) n2 + n + 100 (c) 1024 n (d) + 10000 100 (e) n2 + n3 (f) n2 + n log n + n (g) n3/2 + n 2. Determine the O() performance of each of these segments of code. Explain your answers. (a) for (int i = 0; i < n; i++) { count++; } (b) for (int i = 0; i < 1000; i++) { count++; } (c) for (int i = 0; i < n; i++) { for (int j = 0; j < n; j++) { count++; } } (d) for (int i = 0; i < n; i++) { for (int j = i; j < n; j++) { count++; } } (e) for (int i = 0; i < n; i++) { for (int j = 0; j < 1000; j++) { count++; } } 3.

D) Measure the performance of selection sort as in Exercise 11. (e) Compare selection sort with insertion sort in terms of how sensitive the performance of each is to the order of the original data. 3. It works by checking each item, one by one, until it finds the search target. Linear search has O(n) performance, which is reasonable if the list of elements is not too long. However, if an array is sorted, then a more efficient divide-and-conquer strategy can be used. It compares the target with the middle item in the array.

It is declared as type int[], and so the item type for an enhanced for-loop using that array should be int. println(item); } The enhanced for-loop is quite nice in situations when you do not otherwise need the array indices. 3 solves the search problem: Given an array data and a particular value target, determine whether or not target appears as an element in data. If it does, return the smallest index where it occurs; otherwise, return −1. We solve the search problem by producing an algorithm.
