Pseudo-code for stack operation

Here's a simple pseudo-code for basic stack operations:

<code>initialize stack
push(value): if stack is full: print "Stack Overflow" else: stack[top] = value top = top + 1
pop(): if stack is empty: print "Stack Underflow" return None else: top = top - 1 return stack[top]
peek(): if stack is empty: print "Stack is empty" return None else: return stack[top - 1]
</code>

This pseudo-code includes functions for pushing a value onto the stack, popping a value from the stack, and peeking at the top value without removing it.
