For each of the following, give an exact formula T(n) for the number of times //op is run: (assume i+=1 each iteration unless otherwise specified) Ex. T(n) =n for i 1 to n do // constant time operation for i = 1 to 4n do 1/ constant time operation for i = 1 to n*n*n do // constant time operation for i 1 to 4n do for j - 1 to i do //constant time operation for i 1 to n*n do for j - 1 to i do //constant time operation for i -1 to n do for j - 1 ton do for k 1 to n do // constant time operation for(int i-0; i1; i/-2) // constant time operation<>
