First, describeThis paper analyzes and compares the binary search algorithm of JDK and the common binary search algorithm written by itself, uses bits unsigned right shift to replace the 2 operation, and uses the method of generating random number to produce a range of random number array, and calls the sort () static method of the arrays class to sort the array of int type.math.random () Usage: Generates a

Binary Search/binary search algorithm, Binary Search Algorithm Binary Search, also known as semi-query, has the advantage of a small number of times, fast query speed, and good average performance. Its disadvantage is that the table to be queried is an ordered table and it is difficult to insert or delete data. Therefo

Binary Search is very simple. Attention must be paid to some details about the deformation of binary search. 1. When you find the first element greater than or equal to the key or the last element smaller than or equal to the key, The loop condition is low However, you need to determine whether the conditions are met when the loop exits; 2. If the last condition is met, When the lower limit is moved, low
