Since most of the code above is binary search, you can leverage the binarySearch(...) provided in the std library and examine the value of the insertion point: public static int usingBinarySearch(int value, int[] a) { if (value <= a[0]) { return a[0]; } if (value >= a[a.length - 1]) { return a[a.length - 1]; }

Jun 23, 2013 · You can use java.util.Arrays.binarySearch for that. It returns: index of the search key, if it is contained in the array; otherwise, (- insertion point - 1). The insertion point is defined as the point at which the key would be inserted into the array. So if the vector q is in the array, you find its index and its neighbours are closest to it.

Apr 11, 2025 · Binary search is a highly efficient searching algorithm used when the input is sorted. It works by repeatedly dividing the search range in half, reducing the number of comparisons needed compared to a linear search.

May 2, 2014 · Given a non-empty binary search tree and a target value, find the value in the BST that is closest to the target. Java Solution 1 – Recursion. Recursively traverse down the root. When target is less than root, go left; when target is greater than root, go right.

Mar 25, 2022 · return binarySearch(array, start, m-1, target); else . return binarySearch(array, m+1, end, target); Instead of returning -1, I want to increase "target" value by 1, until there is a nearest larger matching value. I tried this, but got error... for (int i = end; i < array1.length-end+1; i++) { target += 1; if (target == array1[i]) { break;}

Nov 25, 2024 · In Java, the Arrays.binarySearch() method searches the specified array of the given data type for the specified value using the binary search algorithm. The array must be sorted by the Arrays.sort() method before making this call. If it is not sorted, the results are undefined. Example:

Nov 21, 2018 · Today, I work on a version of binary search that finds the nearest value to the target. The question: Given a sorted bit array of integers, and a target value, find the number in the array that is closest to the target. Parameters Input: arr {Array of Integers} Input: target {Integer} Output: {Integer}

int binarySearch(int array[], int element, int low, int high) { // Repeat until the pointers low and high meet each other while (low <= high) { // get index of mid element int mid = low + (high - low) / 2; // if element to be searched is the mid element if (array[mid] == element) return mid;

Mar 13, 2023 · This code uses the binary search algorithm to search for a target value in a sorted array. It takes an array arr and a target value target as inputs, and returns the index of the target value if it is found in the array.

Feb 14, 2020 · How to search a target value in a sorted array using Binary Search. In this tutorial, You are going to learn Binary search algorithm and it’s code implementation in java. Before implementing this algorithm, let’s first understand what is binary search and how it works. i) Binary search is a searching algorithm which works with a sorted array.
