In Stack What Are The Conditions Of Underflow And Overflow?

Here we will learn about In Stack and What Are The Conditions Of Underflow And Overflow? As Overflow is a condition when we try to add a new element in a stack but there is not enough s[space means the stack is already filled and in a can of underflow when we try to delete the element from a stack that is already empty.

This means there is now an element least to be deleted such a condition is called underflow.

Stack

Stack is a data structure that is used to store the data in FILO which means first in last out which stores the data in a just like books kept on the table where if we want to add a new book we need to add it on top and to remove also we have to remove from the top.

This means we can perform deletion and addition from the same end and that is what we call one end opening. There are some conditions so let’s discuss them one by one.

Overflow Conditions

It is a condition when we try to enter the elements but there is no enough space available in a stack to store it. Let’s understand the condition with examples and the syntax of the condition to be written

public static boolean willAddition Overflow(int left, int right) {
    if (right < 0 && right != Integer.MIN_VALUE) {
        return willSubtraction Overflow(left, -right);
    } else {
        return (~(left ^ right) & (left ^ (left + right))) < 0;
    }
}

Here the example shows the condition which needs to check for overflow of the stack before adding new elements to it.

Underflow Condition

As we know underflow condition occurs when we are deleting an element but there is no such element that exists in fact there is no element that could be removed or deleted so that scenario is called underflow.

Now let us understand more with help of an example of code.

public static boolean willSubtraction Overflow(int left, int right) {
    if (right < 0) {
        return willAddition Overflow(left, -right);
    } else {
        return ((left ^ right) & (left ^ (left - right))) < 0;
    }
}

Here we can see how the first checking of the condition is done before removing or deleting the elements from a stack is done just to avoid underflow conditions.
