Sort an integer array, keeping first in place in JavaScript
We are required to write a JavaScript function that takes in an array of Numbers. The function should sort the array according to the following conditions −
array[0] should keep its place
with the next highest integer(s) following (if there are any)
then ascending from the lowest integer
For example −
If the input array is −
const arr = [10, 7, 12, 3, 5, 6];
Then the output should be −
const output = [10, 12, 3, 5, 6, 7];
Example
Following is the code −
const arr = [10, 7, 12, 3, 5, 6];
const uniqueSort = (arr = []) => {
const first = arr[0];
const sorter = (a, b) => {
return (a < first) - (b < first) || a - b;
};
arr.sort(sorter);
};
uniqueSort(arr);
console.log(arr);Output
Following is the output on console −
[10, 12, 3, 5, 6, 7]
