QuickSort: An Algorithmic Deep Dive
Written by
Implementing and visualizing the QuickSort algorithm.
Sorting is a fundamental concept in computer science. Let's look at QuickSort.
Implementation
typescript
function quickSort(arr: number[]): number[] {
if (arr.length <= 1) {
return arr;
}
const pivot = arr[arr.length - 1];
const left = [];
const right = [];
for (let i = 0; i < arr.length - 1; i++) {
if (arr[i] < pivot) {
left.push(arr[i]);
} else {
right.push(arr[i]);
}
}
return [...quickSort(left), pivot, ...quickSort(right)];
}Logic Flow
