How to useRecursive function in Javascript
The recursive approach, represented by the GrayCode function, generates n-bit Gray Codes by building upon smaller code sequences through recursion and bitwise operations, returning an array of Gray Codes.
Syntax:
function GrayCode(n) {
for (let i = 0; i < code1.length; i++) {
}
return;
};
Example: In this example, the GrayCode function generates n-bit Gray Codes recursively. For n=0, it returns [‘0’], and for n=1, it returns [‘0’, ‘1’]. For n>1, it combines previous sequences using bitwise operations and returns an array of Gray Codes.
Javascript
function GrayCode(n) { return n === 0 ? [ '0' ] : n === 1 ? [ '0' , '1' ] : (() => { let code1 = GrayCode(n - 1); let resultCode = []; for (let i = 0; i < code1.length; i++) { resultCode[i] = '0' + code1[i]; resultCode[2 ** n - 1 - i] = '1' + code1[i]; } return resultCode; })(); } // Change this to generate n-bit Gray Codes let n = 2; let result = GrayCode(n); console.log(result); |
[ '00', '01', '11', '10' ]
JavaScript Program to Generate n-bit Gray Codes
In this article, we are going to learn about Generate n-bit Gray Codes in JavaScript.Generating n-bit Gray Codes in JavaScript means creating a sequence of binary numbers of length n where each adjacent number differs by only one bit, typically starting with 0 and 1.
There are several methods that can be used to Generate n-bit Gray Codes in JavaScript, which are listed below:
- Using bitwise XOR and right-shifting operations
- Using Recursive
We will explore all the above methods along with their basic implementation with the help of examples.
