Exercise 3-1. Our binary search makes two tests inside the loop, when one would suffice (at the cost of more tests outside). Write a version with only one test inside the loop and measure the difference in run-time. The standard K&R binsearch performs two comparisons per iteration — it checks x < v[mid], then x …
C Program to find the substring in a String using the Horspool method. This algorithm uses the Brute-Forse method which searches the text between 0 and n-m, and after each cycle it shifts the pattern by one position to the right.

Linear search (also called sequential search) is the simplest searching algorithm: start at the first element, compare each element to the key, and stop when you find a match or exhaust the array. It makes no assumption about the data being sorted. It runs in O(n) time and O(1) space — no extra memory needed …
Binary search in C finds a target value in a sorted array by repeatedly halving the search space. At each step it compares the target against the middle element: if they match, the search is done; if the target is smaller, discard the right half; if larger, discard the left half. This gives O(log n) …
