<p><u>Стек (stack)</u> - это линейная структура данных, подчиняющаяся логике "последним пришел - первым вышел".</p>
<p>Стек можно сравнить со стопкой тарелок на столе. Если разрешено перемещать только одну тарелку за раз, то, чтобы достать тарелку снизу, сначала придется по одной убрать все тарелки сверху. Если заменить тарелки различными элементами (например целыми числами, символами, объектами и т.д.), получится структура данных "стек".</p>
<p>Как показано на рисунке 5-1, верхнюю часть стопки элементов мы называем "вершиной стека", а нижнюю - "основанием стека". Операция добавления элемента на вершину называется "push", а операция удаления верхнего элемента - "pop".</p>
