Amicable Pair Number

 //Wap to accept two numbers and check it is amicable numbers or not.

//the sum of the factor of the first number is equal to the second number and the sum of the factor of

//the second number is equal to the first number, then it is an amicable pair.

//ex- (220,284) are amicable pair

//sum of factors 220=(1,2,4,5,10,11,20,22,44,55,110)=284

//sum of factors 284=(1,2,4,71,142)=220
