// we need to distribute the number of candies , so we need the total number of candies first and then by observation
// we can see that if the number of totla candies are odd then the given condition will meet else not possible 
// here is example
// if the total number of candies are 5 then:
// 3 for sammy and 2 for simmy can be given and no other combination is possible 
// if the total number of candies are 4 then:
// possible combination are:
// 2 2 // first condition not met
// 3 1 // second condition not met
