Please write in python and please do steps 1 and 2. Thank you!

Problem 4 Step 1 Determine the running time equation of this program. Next, use to specify the lower bound complexity of the running time function. 0]: defprob(L):total=10forxinL:total+=xx+5foriinrange(0,len(L)):forjinrange(i+3,len(L)):total+=L[i]L[j]+2returntotal Step 2 Determine the running time equation of the program in the problem above. Next, use O to specify the upper bound complexity of the running time function
