Question

For some calculations, we want an algorithm that accepts only positive integers up to 100.

Accept_1 to 100_Algo
INPUT Number
IF (0 <= Number) AND (Number <= 100)
       ACCEPT
Else
       REJECT

1. On what values will this algorithm fail?
2. Can you improve the algorithm?

Answer 1

If we enter 0 then this algorithm will fail.

Correct algorithm:

INPUT Number
IF (0 < Number) AND (Number <= 100)
   ACCEPT
   Else
      REJECT
