arrayImpOfStack.java如何反转输出中的数字？

public void reverseStack(Stack<Integer> stack) {
    Stack<Integer> tempStack = new Stack<>();
    while (!stack.isEmpty()) {
        tempStack.push(stack.pop());
    }
    // 此时tempStack中的元素顺序与原始stack相反
    // 如果需要，可以将tempStack的内容复制回原始stack
    while (!tempStack.isEmpty()) {
        stack.push(tempStack.pop());
    }
}

public void reverseStackUsingRecursion(Stack<Integer> stack) {
    if (!stack.isEmpty()) {
        int temp = stack.pop();
        reverseStackUsingRecursion(stack);
        insertAtBottom(stack, temp);
    }
}

private void insertAtBottom(Stack<Integer> stack, int item) {
    if (stack.isEmpty()) {
        stack.push(item);
    } else {
        int temp = stack.pop();
        insertAtBottom(stack, item);
        stack.push(temp);
    }
}

public void reverseStackUsingArray(Stack<Integer> stack) {
    int[] array = new int[stack.size()];
    for (int i = 0; i < array.length; i++) {
        array[i] = stack.pop();
    }
    for (int i = array.length - 1; i >= 0; i--) {
        stack.push(array[i]);
    }
}
