  *
 * You'll be given a list of activities and their caloric impact.
 * Write a program that outputs the names of activities one should choose to partake in
 * so that the sum of their caloric impact is zero.
 * Once an activity is selected, it cannot be chosen again.
 *
 * It is a question to find a sum to zero from all possible elements of an array
 * Basically use gray code to pick element from a given array and calculate the sum
