 * 		FIND THE SMALLEST WIHTOUT USING < AND > SYMBOL
 * 
 * 	Write a java program to find the smallest among a, b, c
 *  without using < AND > symbol.
 *  
 *  For comparing two numbers we need to use the relational operator.
 *  
 *  The alternate idea is to find the divisor of a / b,
 *  if result is 0 then a is small, else b is small
 *  
 *  Then apply same logic with the result like c / a or c / b
