this is my code:
i think it is better because i didn't have to think of any edge cases.
class Solution {
public:
ListNode* mergeNodes(ListNode* head) {
ListNode *dummy=head;
ListNode *curr=dummy;
int sum=0;
ListNode *temp=head;
temp=temp->next;
while(temp){
if(temp->val!=0){
sum+=temp->val;
temp=temp->next;
}else{
if(sum!=0){
curr->next=new ListNode(sum);
curr=curr->next;
}
sum=0;
temp=temp->next;
}
}
ListNode *ans=dummy->next;
delete dummy;
return ans;
}
};

what about the case where there are two consecutive 0 nodes? is this case being handeled as there shouldn't be 0s in the resulatant list.
