Debugging is an art that every successful programmer needs to master sooner rather than later. The sad truth is that program bugs appear almost as soon as you start coding.

‘ ShellSort. A compact routine that sorts data in place (no extra memory ‘ needed) and runs in O(N (log N)^2) time. Not stable (does not preserve ‘ original order
‘ QuickSort. QuickSort, CombSort and ShellSort all exploit the principle of ‘ exchanging keys that are far apart in the list rather than adjacent. ‘ QuickSort does this most elegantly
‘ MSD RadixSort. No sort based on comparisons can be faster than O(N log N). ‘ RadixSort makes no comparisons and can therefore achieve O(N) behavior. To ‘ do this,
‘ InsertionSort. A simple routine with minimal overhead. Should never be used ‘ to sort long lists because of its O(N^2) behavior,’ but is the method of choice for sorting
‘ Ternary QuickSort. See the summary of QuickSort for background before ‘ reading this one. Ternary QuickSort (also called MultiKey QuickSort) differs ‘ from the original QuickSort by examining keys
