push('Hello'); $stack->push('World'); $value = $stack->peek(); echo $value; // Outputs: World ?>
StackIn this example, we create a new stack using the Stack class, push three integer values onto it, and then retrieve the top value using the Peek method. Finally, we print the value to the console. Overall, PeekValue is a useful function for retrieving values from the top of a stack without affecting its contents, and can help in various data processing scenarios.numberStack = new Stack (); numberStack.Push(10); numberStack.Push(20); numberStack.Push(30); int value = numberStack.Peek(); Console.WriteLine(value); // Outputs: 30
