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 …
Exercise 5-15. Add the option -f to fold upper and lower case together, so that case distinctions are not made during sorting; for example, a and A compare equal. Add a fold flag. When set, the comparison function converts both characters to lowercase before comparing. The key: don’t modify the strings themselves — do the …
Exercise 5-16. Add the -d (directory order) option, which makes comparisons only on letters, numbers and blanks. Make sure it works in conjunction with -f. Directory order ignores punctuation and control characters — only alphanumeric characters and spaces are considered. The comparison function skips non-directory characters in both strings simultaneously, then compares the next significant …
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 …
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.

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 …
