Crawler Log Folder - Solution & Explanation

This approach involves maintaining a counter to keep track of the current folder depth. For each log operation, adjust the counter accordingly:

• For "x/" operations, increment the counter since we're going deeper into the directory structure.
• For "../" operations, decrement the counter but ensure it doesn't go below zero since we can't go above the root directory.
• For "./", do nothing as it indicates staying in the same directory.

After processing all the logs, the counter will give the minimum operations needed to return to the main folder, as it represents the current depth.

The C implementation uses the strcmp function to compare strings for directory operations and adjusts a counter representing the current directory depth. The final value of the counter gives the required number of operations to get back to the main folder.

This approach simulates navigating through folders using a stack. The stack keeps track of folder paths:

• For "x/", push the folder onto the stack.
• For "../", pop from the stack unless it's empty (indicating the root).
• For "./", do nothing, as it indicates staying in the same directory.

The stack's size at the end represents the current depth, which is the number of operations needed to return to the main folder.

The C solution mimics the behavior of a stack using an integer counter to track how many directories down the user is. It simulates pushing and popping with integer operations.
