Merge Sort in C – Algorithm, Program, and Complexity

Merge sort in C is a classic divide-and-conquer sorting algorithm that guarantees O(n log n) time in all cases. It splits an array into halves, recursively sorts each half, then merges the sorted halves back together. Unlike bubble sort or insertion sort, merge sort never degrades to O(n²) — making it the preferred choice when …

C Program to generate random numbers.

C Program to generate random numbers. Random Numbers are numbers which are produced by a process and its outcome is unpredictable.The function srand() is used to seed the random sequence. The rand() function shall compute a sequence of pseudo-random integers in the range [0, {RAND_MAX}] with a period of at least 2^32. Read more about …

C program to find the 2’s complement of a binary number.

C Program to calculate the 2’s complement of a binary number. 2’s complement of a number is obtained by scanning it from right to left and complementing all the bits after the first appearance of a 1. Thus 2’s complement of 11100 is 00100. Read more about C Programming Language . /************************************************************ You can use …

C Program to Implement Heap Sort — Algorithm, Tree Visualization, and Complexity

Heap Sort is a comparison-based sorting algorithm that uses a binary heap data structure. Its standout property: it is guaranteed O(n log n) in all cases — best, average, and worst — while using only O(1) extra memory. No Quick Sort worst-case surprises, no Merge Sort extra array. Key Concept — The Max-Heap A max-heap …
