Explanation Given information: A = { a [ 1 ] , a [ 2 ] , ... , a [ n ] } . Calculation: We need to create an algorithm that will check if some relation is reflexive. The input will be a relation R on a set A = { a | 1 | , a | 2 | , ... , a | n | } Input: A = { a [ 1 ] , a [ 2 ] , ... , a [ n ] } , R [ a r e l a t i o n o n t h e s e t A ] For each element a in A, we will need to check if ( a , a ) ∈ R . if we find some a such that ( a , a ) ∉ R , then the algorithm will need to return that the relation is not reflexive, else the algorithm will need to return that the relation is reflexive. Algorithm body: a n s w e r : = " reflexive" i : = 1 while i ≤ n and a n s w e r = " reflexive" if ( a
