What is the time complexity of the following code snippet?int sum = 0;...
The time complexity of the code snippet is O(n), where n is the value of the variable n. This is because the code snippet contains a single for loop that iterates n times. Within each iteration of the loop, there is a constant time operation (adding 1 to the sum), so the overall time complexity is proportional to the number of iterations of the loop, which is n.
