Answer:
- Sort the array from smallest to largest.
- Iterates through the sorted array, fetching the first k elements.
/ * * *@param {number[]} arr
* @param {number} k
* @return {number[]}* /
var getLeastNumbers = function(arr, k) {
let result = []; // Store the result
arr.sort((a, b) = > a - b); // Sort the array from smallest to largest
// Retrieves k elements from sorted array
for (let i = 0; i < k; i++) {
result.push(arr[i]);
}
return result;
};
Copy the code/ * * *@param {number[]} arr
* @param {number} k
* @return {number[]}* /
var getLeastNumbers = function(arr, k) {
return arr.sort((a, b) = > a - b).splice(0, k)
};
