How to solve out of range

"Out of range" errors usually indicate an attempt to access an index or key in an array or collection that does not exist. Before solving this problem, you need to determine which index or key is out of range. Here are some common solutions:

1. Check that the index or key is correct: Make sure that the index or key you use when accessing the array or collection is valid. If you use a loop to iterate over an array or collection, make sure the upper limit of the loop is correct.

2. Check the size of an array or collection: Before accessing an array or collection, make sure you know its size. If you try to access an index or key that exceeds the size, an "out of range" error will result.

3. Use bounds checking: Before accessing an array or collection, you can check whether the index or key is within a valid range. For example, you can use a conditional statement to check whether an index is out of bounds when accessing an array.

4. Use exception handling: In some programming languages, you can use exception handling to catch "out of range" errors and take appropriate action when an error occurs.
