# JavaScript Program to Find array sum using Bitwise OR after splitting given array in two halves after K circular shifts

We will write a JavaScript program to find the sum of an array by using bitwise OR after splitting the given array into two halves after K circular shifts. Our program will perform the task by taking an array and an integer K as inputs. First, we will split the array into two halves after performing K circular shifts. Then, we will perform bitwise OR on both the halves to get a new array. Finally, we will find the sum of the new array obtained from the bitwise OR operation.

## Approach

First, perform K circular shifts on the given array.

Split the shifted array into two halves.

Perform a bitwise OR operation on each element of both halves of the array.

Sum up all the elements obtained from step 3 to get the result.

Return the result as the sum of the array after performing the bitwise OR operation and splitting the array into two halves.

## Example

Here is an example of how you can find the sum of an array using Bitwise OR after splitting the array into two halves after K circular shifts −

function splitArrayAndGetSum(array, k) { let splitArray = []; let sum = 0; // Split the array into two halves after K circular shifts for (let i = 0; i < array.length; i++) { splitArray[i % 2] = splitArray[i % 2] | array[(i + k) % array.length]; } // Get the sum of the two halves using Bitwise OR for (let i = 0; i < splitArray.length; i++) { sum = sum | splitArray[i]; } return sum; } let array = [1, 2, 3, 4, 5, 6, 7]; let k = 3; console.log(splitArrayAndGetSum(array, k));

## Explanation

The function takes an

**array**and an integer k as inputs.The variable

**splitArray**is used to store the two halves of the array after it has been split.The variable

**sum**is used to store the sum of the two halves of the array.In the first for loop, the array is split into two halves after

**k**circular shifts. The array is split into two halves using the modulo operator**%**. The value of each element in the two halves is obtained using the bitwise OR operator**|**with the value of the corresponding element in the original array after**k**circular shifts.In the second for loop, the sum of the two halves is obtained using the bitwise OR operator

**|**. The final result is stored in the variable**sum**.Finally, the

**splitArrayAndGetSum**function returns the value of sum.
