here is a basic outline: * Split the list into two halves * Recursively sort each half * Merge the two sorted halves into a single, sorted list You can use other sorting algorithms like quicksort or bubble sort. If you need help with implementation or want a more detailed example, just let me know!Here is an example of how you can sort a linked list using the merge sort algorithm: function ListNode(val) { this.val = val; this.next = null; } function mergeSortList(head) { if (!head || !head.next) { return head; } let fast = head; let slow = head; let prev = null; while (fast && fast.next) { prev = slow; slow = slow.next; fast = fast.next.next; } prev.next = null; const l1 = mergeSortList(head); const l2 = mergeSortList(slow); return merge(l1, l2); } function merge(l1, l2) { const dummy = new ListNode(); let curr = dummy; while (l1 && l2) { if (l1.val < l2.val) { curr.next = l1; l1 = l1.next; } else { curr.next = l2; l2 = l2.next; } curr = curr.next; } curr.next = l1 || l2; return dummy.next; } const head = new ListNode(4); head.next = new ListNode(2); head.next.next = new ListNode(1); head.next.next.next = new ListNode(3); const sortedHead = mergeSortList(head); let current = sortedHead; while (current) { console.log(current.val); current = current.next; }
