LeetCode 763: Partition Labels — Step-by-Step Visual Trace
📰 Dev.to · tracelit
Learn to solve LeetCode 763 by partitioning a string into parts where each letter appears in at most one part, and return the size of these parts
Action Steps
- Read the input string s and initialize an empty list to store the size of the partitions
- Create a dictionary to store the last occurrence of each character in the string
- Initialize two pointers, start and end, to represent the current partition
- Iterate over the string and update the end pointer to be the maximum of its current value and the last occurrence of the current character
- When the end pointer is equal to the current index, it means we have found a valid partition, so add its size to the result list and update the start pointer
- Return the list of partition sizes
Who Needs to Know This
This problem is beneficial for software engineers and developers who want to improve their coding skills, especially in string manipulation and partitioning. It can be useful in a team setting where developers need to work on text processing tasks.
Key Insight
💡 The key to solving this problem is to use a dictionary to store the last occurrence of each character and update the end pointer accordingly
