Searching a bitonic array is known as bitonic search. An array is said to bebitonicif it has an increasing sequence of integers followed immediately by a decreasing sequence of integers. Given abitonic arrayour work is to search a given input element in thebitonic array. In case of minimum ...
Earlier in this article, we saw that we can use binary search to find a key in a sorted range. We discussed based on integer element. In this article, we are going to discuss based on asorted list of strings. The idea is exactly similar, the similar the only difference is the data ...
