1. For each of the following code snippets, find the asymptotic running time (i.e. e). Justify your answer in the same way we did in class: find an expression for the running time as a function of n, then find a valid upper and lower bound which differ by only a constant factor. (a) Func1(n) S=0 for i=1 to n do for j = 1 to n do s=s+i+j return s (b) Func2(n) s=0 for i=1 to n do for j = 1 to 1 do s=s+i+j return s (c) Func3(n) 8=0 for i=1 to n do for j = 1 to n do return s for k = 1 toj do s=s+i+j
