🌋 Find All K-Distant Indices in an Array – LeetCode 2200 (C++ | Python | JavaScript)
- LeetCode problem 2200 involves finding all k-distant indices in an array, where an index i is considered k-distant if there is at least one index j such that |i - j| <= k and nums[j] == key.
- The efficient solution for this problem involves a greedy strategy using pointers, where for each index j where nums[j] == key, all indices i within [j - k, j + k] are added to the result set, covering all valid i within the distance k from the key position.
- The C++, JavaScript, and Python solutions provided linearly process the array, ensuring old indices are not rechecked, resulting in a time complexity of O(n) and space complexity of O(1) apart from the output.

Why Understanding Try-Except in Python is Essential for Every Programmer
- Try-except block in Python is crucial for handling errors that may occur during program execution.
- It helps in preventing unexpected crashes, especially when dealing with user input that can be unpredictable.
- The try block contains the code that might raise an error, while the except block specifies what to do if an error occurs.
- Additional keywords like else and finally can also be combined with try-except for more robust error handling.
- Using try-except allows programs to handle various types of errors, such as ValueErrors, without halting execution.
- Properly handling errors ensures smooth program execution and minimizes unexpected crashes.
- While try-except is beneficial, it's important to be cautious about its usage, such as catching specific errors and providing helpful messages to users.
- Avoid using a general except block and ensure that try-except is applied judiciously in areas where errors are likely to occur.
- By utilizing try-except along with effective error handling practices, Python programs can become more robust and user-friendly.
