you create an integer array whose index range covers the entire range of values in your array to sort. Each time a value occurs in the original array, you increment the counter at that index. At the end, run through your counting array, printing the value of each non-zero valued index ...

In an array, , the elements at indices and (where ) form an inversion if . In other words, inverted elements and are considered to be "out of order". To correct an inversion, we can swap adjacent elements. For example, consider the dataset . It has two inversions: and . To sort th...
Complete the countSort function in the editor below. It should construct and print the sorted strings. countSort has the following parameter(s): string arr[n][2]: each arr[i] is comprised of two strings, x and s Returns - Print the finished array with each element separated by a ...
