6: (10 points) Assume that T(n) for the following code segment tells us exactly how many times the instructionx -x 1 is executed for some given n. for i in range(o, n): for j in range (1, 2*n): for k in range (0, (6*n)//3): for m in range(1, 4): print(x) 6a: If the value of n is 3, what is the value of x when it is printed? 6b: What is the best O-notation for T(n)? (Or in other words, what is the most appropriate Big O for this code segment?) Explain your reasoning
