Sort a linked list using insertion sort.
class Solution { public: ListNode *insertionSortList(ListNode *head) { if(head == NULL || head->next == NULL) return head; ListNode *result; result->val = INT_MIN; result->next = NULL; ListNode *cur=head,*pos,*pre; while(cur!=NULL) { pos = result->next; pre = result; while(pos != NULL && pos->val <= cur->val) { pre = pos; pos = pos->next; } ListNode *temp = cur->next; pre->next = cur; cur->next = pos; cur = temp; } return result->next; } };
