In this example, we are creating a tuple of 5 numbers and using sum() on the dictionary in Python. Output : Time complexity: O(1) Space complexity: O(n)
In this example, we are creating a tuple of 5 numbers and using sum() on the set in Python. Output :
In this example, we are creating a tuple of 5 numbers and using sum() on the tuple in Python. Output : Time complexity: O(1) Space complexity: O(n)
In this, the code first defines a list of numbers. It then initializes a variable called total to 0. The code then iterates through the list using a for loop, and for each number in the list, it adds that number to the total variable. Finally, the code prints the total value, which is the sum of the numbers in the list. Output : Time complexity: O(...
TypeError : This error is raised when there is anything other than numbers in the list . In the given example we are using a list of strings rather than an integer. Output :
Problems where we require the sum to be calculated to do further operations such as finding out the average of numbers. Output
