JavaScript Program to Add n Binary Strings
Last Updated :
31 May, 2024
In this article, we are going to learn about Adding n binary strings by using JavaScript. Adding n binary strings in JavaScript refers to the process of performing binary addition on a collection of n binary strings, treating them as binary numbers, and producing the sum in binary representation as the result.
There are several methods that can be used to Add n binary strings by using javascript, which is listed below:
We will explore all the above methods along with their basic implementation with the help of examples.
Using for...in loop
In this approach, The custom function sums binary strings in inputStr using a for...in loop, converting them to decimal, and returning the result as a binary string
Syntax:
for (let i in obj1) {
// Prints all the keys in
// obj1 on the console
console.log(i);
};
Example: In this example,The addBinaryStrings function takes an array of binary strings, converts them to decimal, adds them together, and returns the sum as a binary string.
JavaScript
function addBinaryStrings(str1) {
let result = 0;
for (let i in str1) {
result += parseInt(str1[i], 2);
}
return result.toString(2);
}
let inputStr = ['0111', '1001'];
let sum = addBinaryStrings(inputStr);
console.log(sum);
Using reduce() method
In this approach, using Array.reduce(), define a function that takes an array of binary strings, converts them to decimal, accumulates their sum, and returns the result as a binary string. The accumulator starts at "0".
Syntax:
array.reduce( function(total, currentValue, currentIndex, arr),
initialValue );
Example: In this example,the addingBinaryStr function takes an array of binary strings, converts them to decimal, adds them with reduce, and returns the sum as a binary string.
JavaScript
function addingBinaryStr(str1) {
return str1.reduce((val1, val2) => {
let binary1 = parseInt(val1, 2);
let binary2 = parseInt(val2, 2);
let sum = binary1 + binary2;
return sum.toString(2);
}, "0");
}
let inputStr = ['0111', '1001'];
let result = addingBinaryStr(inputStr);
console.log(result);
Using parseInt() and toString() method
In this approach,we Add binary strings by converting them to integers using parseInt with base 2, then summing them, and finally converting the result back to binary using toString(2).
Syntax:
parseInt(Value, radix) //parseInt()
num.toString(base) //toString()
Example: In this example, we are using above-explained approach.
JavaScript
let binary1 = "0111";
let binary2 = "1001";
// Parse binary string 'binary2' to an integer
let num1 = parseInt(binary1, 2);
// Parse binary string 'binary2' to an integer
let num2 = parseInt(binary2, 2);
// Add the two integers
let sum = num1 + num2;
// Convert the sum back to a binary string
let result = sum.toString(2);
console.log(result);
Bitwise Addition
In this approach, we perform binary addition using bitwise operations. We traverse each bit of the binary strings from the least significant bit (rightmost) to the most significant bit (leftmost). We maintain carry during addition and update the result accordingly.
Example:
JavaScript
function addBinaryStrings(str1) {
let result = '';
let carry = 0;
// Iterate through each bit from right to left
for (let i = str1[0].length - 1; i >= 0; i--) {
let sum = carry;
// Add the corresponding bits of all binary strings
for (let j = 0; j < str1.length; j++) {
sum += parseInt(str1[j][i]) || 0;
}
// Calculate current bit of result
result = (sum % 2) + result;
// Calculate carry for the next bit addition
carry = Math.floor(sum / 2);
}
// Add carry if present
if (carry) {
result = carry + result;
}
return result;
}
let inputStr = ['0111', '1001'];
let sum = addBinaryStrings(inputStr);
console.log(sum);
