WebThis class contains various methods for manipulating arrays (such as sorting and searching). This class also contains a static factory that allows arrays to be viewed as lists. The methods in this class all throw a NullPointerException, if the specified array reference is null, except where noted. WebBinary search follows the divide and conquer approach where the list is divided into two halves and the item is compared with the middle element each time. If the middle element is less than the element to be searched, then we search for the element in the first half of the list; otherwise, we search for the element in the second half of the list. WebThe bsearch () function in C++ performs a binary search of an element in an array of elements and returns a pointer to the element if found. The bsearch () function requires all elements less than the element to be searched to the left of it in the array. options delta gamma theta vega rho
