Write C program to implement bucket sort. The idea of Bucket Sort is to divide the interval [0, 1] into n equal-sized sub intervals, or buckets, and then distribute the n input numbers into the buckets. To produce the output, we simply sort the numbers in each bucket and then go through the buckets in …
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 …
