Segregate all 0s on right and 1s on left in JavaScript
We have an array of Numbers that contains 0, 1 and some other numbers. We are required to write a JavaScript function that takes in this array and brings all 1s to the start and 0s to the end
Let's write the code for this function −
Example
const arr = [3, 2, 1, 8, 9, 0, 1, 9, 0, 2, 1, 0, 2, 0, 1, 0, 1, 1, 4, 0,
3];
const segregate = arr => {
const copy = arr.slice();
for(let i = 0; i < copy.length; i++){
if(copy[i] === 0){
copy.push(copy.splice(i, 1)[0]);
}else if(copy[i] === 1){
copy.unshift(copy.splice(i, 1)[0]);
};
continue;
};
return copy;
};
console.log(segregate(arr));Output
The output in the console will be −
[ 1, 1, 1, 3, 2, 8, 9, 1, 9, 2, 2, 1, 1, 4, 3, 0, 0, 0, 0, 0, 0 ]
