Storage structure and basic algorithms programmed sequence stack, including the following features: initialization sequence stack S determine the order whether the stack S is empty sequentially character data type of the element ' a' , ' b' , ' c' , ' d ' ,' e ' stack determine all the elements of the stack S if the sequence is empty sequentially stack order stack S within the stack, the stack and output the results to determine whether the order stack S is empty release order and destroy the stack S
