For each guessed JavaTpoint offers too many high quality services. With binary search, you eliminate half of the data with each decision. If you look at each item in order, you may have to look at every item in the data set before you find the one you are looking for. In computer science, binary search, also known as half-interval search, logarithmic search, or binary chop, is a search algorithm that finds the position of a target value within a sorted array. If the Pivot Element (the item to be searched) is less than the item in the middle of the interval, We discard the second half of the list and recursively repeat the process for the first half of the list by calculating the new middle and last element. Binary trees are used to represent a nonlinear data structure. The "Binary search algorithm" pages says that it's D&C, whereas the D&C page your quote links to, says that D&C by definition involves multiple recursion, which binary search does not. Binary Search.
