Some mathematical numbers are identified by different names. These names are given by different mathematicians. We can establish those numbers, logically by the Java program. For that we first know the mathematical definition of the numbers after then we must think how we can represent programmatically.
Write a program that displays all integers between the low and high that are the sum of cube of their digits. In other words, find all numbers XYZ such that XYZ=X3+Y3+Z3. try 100 for low and 1000 for high. [WBUT MCA 2014]

while(sn<=1000)
{

s=0;
while(n>0)

r=n%10;
s+=Math.pow(r,3);
n /=10;
}

{
System.out.println(sn + "");
}
sn++;
