Counting sort works by iterating through the input, counting the number of times each item occurs, and using those counts to compute each item's index in the final, sorted array. O(n) time!

2.1Insertion Sort - To be honest you should probably know all major sorting algorithms, not just insertion sort. It's just basic knowledge and you never know when it can help. 2.2Analysis of Algorithms - you can skip the small intro, but know the rest. 2.3Designing algorithms - contains m...
Negative Version of Counting SortLinear timeTheta notationRunning sumCounting sort is basically a linear time sorting algorithm. It sorts given array having integer elements ranging from 0 to K (where 'K' is upper limit of integer which can be present in input array). Counting sort can only ...

Using counting sort: 1. Create an array of 8-byte longs that has 2^16 entries. Take your input numbers, shift off the bottom sixteen bits, and create a histogram. this is to create buckets that store ranges of your input data, and find the mid bucket. also record the number of ...
So we're gonna ask our recursive calls to not only count inversions in the array of their past. But also along the way, to sort the array. And hey. Why not? We know sorting is fast. Merge short will do it in N. Log in time, which is the run time we're shooting for. ...
