Give a brief explanation of just-in-time compilation.

While counting sort appears to have the best runtime, it is seldom ever implemented. Why is this the case? What is it about the algorithm that makes it practically undesirable? Be sure to back up your claims with relevant analysis and mathematical arguments.

Is there a way to optimize the following multithreaded quick sort algorithm, in C? I am looking for suggestions to make it run faster. I am trying to get closer to the qsort function's time. I don't want anything too complicated, like thread pooling. Here is the code:    #include <stdio.h>#include <stdlib.h>#include <errno.h>#include <string.h>#include <pthread.h>#include <time.h>#define SORT_THRESHOLD 40typedef struct _sortParams {char** array;int left;int right;int* threadsLeft; // A counter to keep track of how many more threads are available to be created.pthread_mutex_t* mutex;} SortParams;static int maximumThreads; /* maximum # of threads to be used */static void insertSort(char** array, int left, int right) {int i, j;for (i = left + 1; i <= right; i++) {char* pivot = array[i];j = i - 1;while (j >= left && (strcmp(array[j], pivot) > 0)) {array[j + 1] = array[j];j--;}array[j + 1] = pivot;}}/*** This function uses a mutex to…

Is there a way to quickly utilize enumeration types to get frequently used operators like arithmetic and stream operators? Is it feasible, for instance, to overload these operators and get the desired outcome? Exactly why do people have strong feelings either for or against this?
