Bucket Sort in C – Algorithm, Code, and Complexity Explained

Bucket sort is a distribution-based sorting algorithm that works by dividing elements into a fixed number of equally-sized ranges (buckets), sorting each bucket individually, then concatenating the results. It is particularly efficient for uniformly distributed floating-point values in [0, 1) and can approach O(n) average-case time — faster than comparison-based sorts like merge sort or …

Sort a String Alphabetically in C – Case-Sensitive and Case-Insensitive

To sort a string alphabetically in C, apply bubble sort to the character array: compare adjacent characters and swap them when the left character is greater than the right. After all passes, the characters are in ascending ASCII order — digits first, then uppercase A–Z, then lowercase a–z. For a sort that treats ‘A’ and …

C Program to implement address calculation sort.

Write a C Program to implement address calculation sort.Address calculation sort is the sorting method which sorts the given array by using insertion method.In this algorithm, a hash function is used and applied to the each key. Result of hash function is placed in the linked lists. The hash function must be a order preserving …

K&R C Programs Exercise 5-14

Exercise 5-14. Modify the sort program to handle a -r flag, which indicates sorting in reverse (decreasing) order. Be sure that -r works with -n. The K&R sort from Section 5.11 calls qsort with a comparison function strcmp. Adding -r requires the comparison function to negate its result. The cleanest approach: add a global flag …

C Program to implement topological sort.

Write a c program to implement topological sort.Topological sort is the ordering vertices of a directed, acyclic graph(DAG), so that if there is an arc from vertex i to vertex j, then i appears before j in the linear ordering.

C Program to Implement Radix Sort — LSD with Counting Sort Explained

Radix Sort is a non-comparison sorting algorithm — it never compares two elements directly. Instead, it sorts by processing individual digits, one digit position at a time from least significant to most significant (LSD approach). This lets it sort integers in O(n) time for a fixed number of digits, breaking the O(n log n) lower …
