Leetcode Problem 388. Longest Absolute File Path

388. Longest Absolute File Path

Leetcode Solutions

Initialize a stack to keep track of the lengths of the paths at each depth level.
Initialize maxLen to 0 to keep track of the maximum path length to a file.
Split the input string by newline characters to process each file/directory individually.
Iterate over each line in the split input. a. Determine the depth of the current line by counting the number of tab characters. b. Pop elements from the stack until the stack's size is one more than the current depth (to find the parent directory). c. Calculate the current length by adding the length of the current line (excluding tabs) to the top element of the stack and add 1 for the '/' character. d. Push the current length onto the stack. e. If the current line contains a '.', it is a file, so update maxLen if the current length minus 1 (to exclude the trailing '/') is greater than maxLen.
Return maxLen as the result.
