I have var ar = [1, 2, 3, 4, 5] and want some function getSubarray(array, fromIndex, toIndex), that result of call getSubarray(ar, 1, 3) is new array [2, 3, 4].

Use the copyOfRange() to Create a Subarray From an Array in Java. Java provides us with a way to copy the elements of the array into another array. We can use the copyOfRange() method, which takes the primary array, a starting index, and an ending index as the parameters and copies that subarray to the destined array.
The total number of subarrays in an array of size N is N * (N + 1) / 2. The count of subarrays with an odd product is equal to the total number of continuous odd elements present in the array. Therefore, count of subarrays with even product = (Total number of subarrays – Subarrays with the odd product).
A subarray is commonly defined as a part or section of an array. An array is a set of variables that a programmer defines collectively. Instead of creating separate variables, the programmer can declare a single array with multiple values labeled.
Take a look at Array.slice(begin, end)
const ar = [1, 2, 3, 4, 5]; // slice from 1..3 - add 1 as the end index is not included const ar2 = ar.slice(1, 3 + 1); console.log(ar2);If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
