Thread: Determining whether the set is reflexive, symmetric, anti symmetric and transtitive

Don't declare new variables a,b - this is only confusing, use a[i] and b[i] directly.
Anyway I don't understand what you try to accomplish.
Let's try a new thing, leave writing code, describe your algorithm to find reflexive set in words (no code), I believe the algorithm you have in mind isn't good.
Then we will implement it.

set hold to true
for each index i
set a = A[i]
set b = B[i]
set hold to false
for each index j
if A[j] is b
if B[j] is a
set hold to true
break
if hold is false
print "Reflexive - No"
break
if hold is true
print "Reflexive - Yes"
