This course teaches students how to think algorithmically and solve problems efficiently. The best case for binary search, too, is 1 since our item might be in the middle of the array.

It checks whether n<0, which is good, but it is inside the for loop! This means that it will be checked on EVERY pass. Students learn how to think algorithmically and solve problems efficiently. Looking for Fall 2023? This is CS50. Play/Pause: spacebar or k: Rewind 10 seconds: left arrow or j: Fast lfind() and lsearch() perform a linear search for key in the array base which has *nmemb elements of size bytes each.
