Give the upper bound (big O notation) that you can for the following code fragment, as a function of the initial value of n. for(int i = 0; i < n; i++) { for(int j = 0; j < i; j++){ //do swap stuff, constant time } } Do you think that the lower bound is likely to be the same as the answer you gave for the upper bound? In your response state why or why not.
