Chapter 7.11, Problem 7.11.1CP
Program Plan Intro
Array:
An array is defined as a group that consists of similar data types.
- The array size must be specified by an “int” value and not long or short.
- In Java, all arrays are allocated dynamically.
- An array is always indexed, starting from 0.
Selection sort
- Sorting is a process to place the elements in order.
- Selection sort is used to sort the group of data.
- Selection sort finds the smallest element in the array by comparing all the elements.
- The element values in the array are exchanged to place the smallest element in the first position.
- Continuously, it finds the next smallest element and exchanges it in the successive positions.
- The exchange process may place one or more elements in its permanent place.

During the sorting process, count the total number of comparisons between array elements made by each algorithm. You may do this by using a global less-than-or-equal-to function to compare numbers, which increments a count variable each time it is called.3. Repeat this process 5 times to compute the average number of comparisons made byeach algorithm.4. Present these average counts in a table. These counts give you an indication of how thedifferent algorithms compare asymptotically (in big-O terms) for a large value of n.(b) Now compare the same algorithms in terms of practical time, i.e. the actual running time.Simply, repeat the previous example but use the chrono library to compute the actual timestaken by each algorithm, and report the average value…arrow_forward
