binary search java code example

, compared to the root node, and, if not equal to the root node, recursively traverses the left subtree or the right subtree, depending on the value of the lookup and the size of the root node. Until the lookup value is found, the result is output.When a binary sort tree is inserted, the value directly to be inserted is stored in an array using the ArrayList linked list, iterating through the array, passing in the new node value, and continuing to cal

Advantages and Disadvantages The advantage of the binary search algorithm is that the query speed is fast and the average performance is good. Th
