In the given program to find the sum and average of N numbers, what will be the output if the input is: 'Enter the value of N 4' and then the numbers '10 20 30 40'?

Sum of all numbers = 90.00 Average of all input numbers = 22.50
Sum of all numbers = 110.00 Average of all input numbers = 27.50
Sum of all numbers = 100.00 Average of all input numbers = 25.00 (correct)
Sum of all numbers = 100.00 Average of all input numbers = 20.00

What is the time complexity of the linear search algorithm?

O(n) (correct)
O(log n)
O(1)
O(n^2)

In the binary search algorithm, if the key is not found in the sorted array, what is the final value of the `low` and `high` indices?

low = n-1, high = 0
low = 0, high = n-1
low = mid, high = mid
low = mid+1, high = mid-1 (correct)
