correct: {n > 0} count = n; sum = 0; P: {n>0 and count = n and sum = 0} while count 0 do sum = sum + count; count = count 1; end Q: {sum = 1 + 2 +… + n} Please note that you need to do this question in the following steps: a) Find a candidate loop invariant I. Show the induction steps using which you find I. Σn k=1 k - Σn k=1k = 0 c)Show {I and B} S {I} P: {sum + count = n + (n-1) +…. + (count+1) + count} => I: {sum = n + (n-1) +…. + (count+1)} sum = sum + count; Q: {sum = n + (n-1)
