The flowchart to reverse digits of an integer may be explained like this: If its a decimal number you could use modulus function to return the first lowest digit in the integer like 45%10 would give you a 5. By doing that you will have the number reversed. Lets see an example of that
Flow: (Lets take for example 123)
num = 123
loop
print num%10 (prints 3)
num = num/10 (num now is 12 - integer division removes remainder)
end loop
result : 321
