Question
You are given an array of integers stones where stones[i] is the weight of the ith stone. We are playing a game with the stones.
You are given an array of integers stones where stones[i] is the weight of the ith stone.
We are playing a game with the stones. On each turn, we choose the heaviest two stones and smash them together. Suppose the heaviest two stones have weights x and y with x <= y. The result of this smash is:
If x == y, both stones are destroyed, and
If x != y, the stone of weight x is destroyed, and the stone of weight y has new weight y - x.
At the end of the game, there is at most one stone left.
Return the weight of the last remaining stone. If there are no stones left, return 0. Hint: May be Max Heap will help you to solve this problem. Use maxheap.
public class MaxHeapDemo {
public static void main(String[] args) {
MaxHeap maxHeap = new MaxHeap();
int[] numbers = { 10, 2, 5, 18, 22 };
// Add all numbers to the heap
for (int number : numbers) {
maxHeap.insert(number);
System.out.printf(" --> array: %s ", maxHeap.getHeapArrayString());
}
while (maxHeap.getHeapSize() > 0) {
int removedValue = maxHeap.remove();
System.out.printf(" --> removed %d, array: %s ", removedValue,
maxHeap.getHeapArrayString());
}
}
}
