a56138aff60341a09ed6c480	Inventory Update	5		Обновление инвентаря

Description

Сравните и обновите инвентарь, хранящийся в 2D-массиве, против второго 2D-массива новой доставки. Обновите текущие объемы инвентарных количеств (в arr1 ). Если элемент не найден, добавьте новый элемент и количество в массив инвентаря. Возвращаемый массив инвентаря должен быть в алфавитном порядке по позиции. Не забудьте использовать Read-Search-Ask, если вы застряли. Попробуйте подключить программу. Напишите свой собственный код.
