How to use Brute Force In Javascript
In this approach, we start by iterating through the numbers in the given range from left to right. For each number, we perform a bitwise OR operation with the result, updating it accordingly. Before computation, we check for a valid range, ensuring both left and right are greater than 0 and left is less than right. Finally, we return the computed result.
Example: Implementation to compute the bitwise OR of all numbers in a range using brute force approach.
function bitwiseOR(left, right) {
if (left < 0 || right < 0 || left > right) {
console.log("Invalid range");
return;
}
let result = 0;
for (let i = left; i <= right; i++) {
result = result | i;
}
return result;
}
const left = 3;
const right = 7;
console.log(bitwiseOR(left, right));
Output
7
Time Complexity: O(n)
Space Complexity: O(1)
JavaScript Program to Compute the Bitwise OR of all Numbers in a Range
In JavaScript, bitwise operations provide a way to manipulate individual bits of numeric values. The bitwise OR operation (|) combines the bits of two operands, resulting in a new value where each bit is set if it is set in either operand.
