Write a program to calculate Amicable pairs

Amicable pair:

Example:

(220,284), (1184,1210), (2620,2924), (5020, 5564), (6232,6368)

Explanation:

(220,284)

divisors of 220 are 1,2,4,5,10,11,20,22,44,55,110;

sum of divisor =284

divisors of 284 are 1,2,4,71 and 142;

sum of divisors=220

int sum1=0,sum2=0;
for( i=1;i<=(num1/2);i++)
{
if(num1%i==0)
sum1+=i;
}
for( j=1;j<=(num2/2);j++)
{
if(num2%j==0)
sum2+=j;
}
if(sum1==num2)
{
if(sum2==num1)
