Inexperienced OO programmers often implement the following class hierarchy, where a Stack class is defined to be a subclass of List:

CLASS List {      data: array [1..100] of INTEGER;      count: INTEGER:= 0;METHODS      insert (pos: 1..100; value: INTEGER);           require: insert value into List at position pos      delete (pos: 1..100)           ensure: remove value stored at position pos from List      retrieve (pos: 1..100),: INTEGER;           ensure: return value stored at position pos in List}CLASS Stack EXTENDS List {METHODS   push(value: INTEGER)       ensure: append value to end of Stackpop(): INTEGER;       ensure: remove and return value from end of Stack}

Explain why this is a bad use of inheritance.
