1598. Crawler Log Folder | Leetcode Daily Challlenge | tree levels | DSA | Java | Hindi

Problem Name:
1598. Crawler Log Folder
Problem Statement:
The Leetcode file system keeps a log each time some user performs a change folder operation.
The operations are described below:
"../" : Move to the parent folder of the current folder. (If you are already in the main folder, remain in the same folder).
"./" : Remain in the same folder.
"x/" : Move to the child folder named x (This folder is guaranteed to always exist).
You are given a list of strings logs where logs[i] is the operation performed by the user at the ith step.
The file system starts in the main folder, then the operations in logs are performed.
Return the minimum number of operations needed to go back to the main folder after the change folder operations.

Why we can't use == operation to check what difference they both have

[@shashwat_tiwari_st]

@@vivekgosai7913 == is used for address comparison, whereas equals is used for value comparison.
String a = "sha";
String b = "sha";
a==b will be false.
a equals b will be true.. understood?
You can watch String lectures in java dsa playlist, that will be helpful 😄
