RNN stands for Recurrent Neural Network, a type of neural network designed to handle sequential data by maintaining a memory of previous inputs.

• RNNs have loops within their architecture, allowing information to persist.

• They are commonly used in natural language processing, speech recognition, and time series analysis.

• An example of RNN is predicting the next word in a sentence based on previous words.

Display non-repeated elements

• Iterate through the elements and count their occurrences

• Display only those elements with occurrence count of 1

• Use a hash table or dictionary to store the counts

• Time complexity: O(n)

List vs Tuple and use case for Tuple

• List is mutable while Tuple is immutable

• List uses square brackets while Tuple uses parentheses

• Tuple is used when data needs to be protected from modification
