A reasonable invariant for binary search might be for a range [low, high), every … WebOct 17, 2015 · Induction step. Assume that the claim holds for n. For n + 1, it takes 1 comparison to check whether the element n + 1 is equal to k. If not, then we need to check whether element ( ( n + 1) − 1) = n is equal to k, which by the induction hypothesis, requires n comparisons. This completes the proof. induction computational-complexity Share Cite WebJul 11, 2010 · Termination: This is the step where we will prove the correctness of the algorithm. When the loop terminates then value of j=n+1. Again loop invariant is satisfied. This means that Sub-array[1 to n] should be sorted. This is what we want to do with our algorithm. Thus our algorithm is correct. hyatt centric waikiki beach yelp
