Recursive binary search algorithm python

WebNov 15, 2024 · A Python binary search is an algorithm that finds the position of an element in an ordered array. Binary searches repeatedly divide a list into two halves. Then, a search compares if a value is higher or lower than the middle value in the list. There are two ways you can perform a binary search. WebJan 25, 2015 · You can check if the result of the recursive binarySearch call in that block is -1 before you add the indexes: else if (key.compareTo (cards.get (mid)) > 0) { result = binarySearch (cards.subList (mid + 1, cards.size ()), key); if (result >= 0) { return mid + 1 + result; } return -1; } Share Improve this answer Follow edited Dec 6, 2011 at 1:06

WebMar 19, 2024 · The recursive binary search algorithm is a natural match for a recursive function. Our guessing range can be defined by the function find(low, high), whose parameters are the low and high sides. def find(low, high) Midpoint is guessed by the function. If the user says lower, the function calls find(low, mid).
