Question
For the implementation of stack s using an array as the underlying data structure,
after each statement below executes, What is the value of topOfStack?
Assume the initial capacity of the stack is 7 and the characters
in "Happy" are stored on the stack (H pushed on first).
ArrayStack
theData =
topOfStack = 4
s.push('m');
s.pop();
s.peek();
s.push('s');
s.push('t');
char ch1 =
s.pop();
s.pop();
s.push(' ');
char ch2 = s.peek();
s.pop();
s.push('q');
Object
[0] =
[1] =
[2] =
[3] =
[4]=
[5] - null
[6] = null
Character
value = 'H'
Character
value = 'a'
Character
value="p
Character
value = 'p'
Character
value="y
