boundit v0.0.3
Boundit
š JavaScript and TypeScript implementation of lower_bound
and upper_bound
for efficient data searching.
Installation
You can install the package using npm:
npm install boundit
Usage
lowerBound
Returns the index of the first element in the array which is greater than or equal to the target.
import { lowerBound } from "boundit"
const array = [1, 2, 4, 4, 5, 6]
const target = 4
const index = lowerBound(array, target)
console.log(index) // Output: 2
upperBound
Returns the index of the first element in the array which is greater than the target, or the length of the array if no such element is found.
import { upperBound } from "boundit"
const array = [1, 2, 4, 4, 5, 6]
const target = 4
const index = upperBound(array, target)
console.log(index) // Output: 4
binarySearch
Binary search is a fast search algorithm with run-time complexity of O(log n). This search algorithm works on the principle of divide and conquer. For this algorithm to work properly, the data collection should be in the sorted form.
import { binarySearch } from "boundit"
const array = [1, 2, 4, 4, 5, 6]
const target = 5
const index = binarySearch(array, target)
console.log(index) // Output: 4
