How can an infinite loop be fixed in a linked list with double pointers?

edit

An infinite loop in a linked list with double pointers can be fixed by checking the pointers carefully and making sure that they are pointing to valid locations in memory. Here are some steps that can be taken to fix an infinite loop in a linked list with double pointers:

1. Check the initialization of the pointers: Make sure that both the head and tail pointers are initialized properly. They should point to NULL initially.

2. Check the insert() function: If the infinite loop is happening during insertion of a new node, then the insert() function needs to be carefully examined. Check if the pointers are being updated correctly after every insertion.

3. Check the delete() function: If the infinite loop is happening during deletion of a node, then the delete() function needs to be thoroughly examined. Check if the pointers are being updated correctly after every deletion.

4. Use a temporary pointer: While traversing the linked list, use a temporary pointer to keep track of the current node. This will help prevent infinite loops caused by pointers pointing to invalid memory locations.

5. Use a loop counter: To avoid infinite loops caused by circular links within the linked list, use a loop counter to limit the number of iterations in the loop. If the loop counter exceeds a certain threshold, then an error should be thrown.
