The document outlines the process of managing a stack data structure, detailing the conditions that lead to stack overflow and the steps for a successful push operation. It specifies that if the 'top' reaches the size limit of the stack, an overflow error occurs. Otherwise, it describes how to store a new element and increment the 'top' index.

1. initially top=0,
if top reaches the size then stack is overflow,
else push the element at top of the stack and
increament the value top by 1
if (top == size)
return false; // ** overflow error **
else
{
data[top] = newNode.deepCopy();
top = top + 1;
return true; // push operation successful
}
