What is the time complexity of deleting a node from a singly linked list given a pointer to that node?

Step 1: Understand that a singly linked list consists of nodes, where each node has data and a pointer to the next node.
Step 2: When you want to delete a node, you need to have a pointer to that specific node.
Step 3: To delete the node, you cannot just remove it because you need to maintain the link to the next node.
Step 4: Instead of removing the node directly, copy the data from the next node into the node you want to delete.
Step 5: After copying the data, change the pointer of the current node to skip the next node, effectively removing it from the list.
Step 6: This process only involves a few pointer changes and data copying, which can be done in constant time.
Step 7: Therefore, the time complexity for deleting a node when you have a pointer to it is O(1).
