Leetcode Remove Duplicates from Sorted List problem solution YASH PAL, 31 July 2024 In this Leetcode Remove Duplicates from Sorted List problem solution we have Given the head of a sorted linked list, delete all duplicates such that each element appears only once. Return the linked list sorted as well. Topics we are covering Toggle Problem solution in Python.Problem solution in Java.Problem solution in C++.Problem solution in C. Problem solution in Python. class Solution: def deleteDuplicates(self, head: ListNode) -> ListNode: if not head: return current = head if current: while current.next and current: # print(current.val) if current.val == current.next.val: current.next = current.next.next else: current= current.next return head Problem solution in Java. public ListNode deleteDuplicates(ListNode head) { ListNode dummy = head; while(dummy != null && dummy.next !=null){ if(dummy.val == dummy.next.val) dummy.next = dummy.next.next; else dummy = dummy.next; } return head; } Problem solution in C++. class Solution { public: ListNode* deleteDuplicates(ListNode* head) { if (head==nullptr) return 0; struct ListNode* ptr; ptr=head; while (ptr->next != nullptr){ if (ptr->val ==ptr->next->val){ ptr->next=ptr->next->next; } else ptr=ptr->next; } return head; } }; Problem solution in C. struct ListNode* deleteDuplicates(struct ListNode* head){ struct ListNode* cur = head; if(head == NULL) return head; while(cur->next != NULL) { if(cur->val == (cur->next->val)) { cur->next = cur->next->next; } else cur = cur->next; } return head; } coding problems solutions
