Counting Sort Algorithm Counting sort isa sorting algorithmthat sorts the elements of an array by counting the number of occurrences of each unique element in the array. The count is stored in an auxiliary array and the sorting is done by mapping the count as an index of the auxiliary array...
No sorting algorithm can sortnelements in better than O(n log n) time if comparing elements. However, there are other ways of sorting elements if we know some information about those elements in advance. For example, assume that we are asked to sortnelements, but we are informed that each...
What remains of potential school dynamics is concentrated in the set of 367 administrative regular schools not reached by the algorithm. Table 3 Number of years of regular education delivered to the 1999 birth cohort and number of schools providing them; before and after clustering Full size table...
Counting Sort is one of the most efficient and a stable algorithm for sorting. It is simple to understand and easy to implement. A good programmer must know this linear sorting algorithm. This is also a hot topic in many beginner and algorithm based interviews. ...

Yes, Nim can produce code that is at least as fast as the code produced from C++; I have coded the "magic" Legendre algorithm in Nim using the GCC back-end which runs at the same speed or maybe a little faster than the C++ version from which I translated it. V is a newer language...
In order to improve the accuracy of sheep counting and avoid the interference of mutual occlusion caused by different moving speed among sheep, the concept of fusion between the improved YOLOv5x model based on the attention mechanism and DeepSort algorithm is proposed. First, the ECA structure th...
First of all, the process has to be started by a single node, which requires some sort of coordination in the initial phase of the algorithm. Moreover, the estimate of the network size at a specific node can exhibit a large overshoot, and joining or leaving nodes cause large local ...
Experienced Stata users have often seen this advice: Do not loop over observations, as it is usually not the best way to do something. Here, however, is an example running contrary to that advice. The simple algorithm above is a good one; our only problem is translating it to Stata code...
Mike’s general advice is good, but these days GNU grep is fast not so much due to skipping bytes with the Boyer-Moore algorithm, but because it uses a fast, vectorized implementation of memchr in glibc.I’m sure there’s further you could go with the C version: investigate memory-...
