Lambda and def both are keywords that are used to define functions in Python. However, their structure and use cases are different from each other. We have discussed some of the differences between lambda functions and def functions below: Feature Lambda def Definition A lambda function is a on...
Define the Block Class: A block is a unit of data in the blockchain. It typically contains a timestamp A list of transactions The hash of the previous block nonce (a random number).You can define a Block class with these attributes and a method to calculate the block’s hash. Define...

Space complexity- Here the code uses a constant amount of additional space regardless of the size of the input list “lst”. So, The space complexity of the code is O(1). Sample Solution-2: Python Code: # Define a function to find the kth largest element in a list using quickselect ...
