When will stack overflow and stack underflow condition occur insequential organization?

In a sequential organization, a stack overflow condition occurs when there is an attempt to push an element onto a stack that is already full, exceeding its allocated memory limit. Conversely, a stack underflow condition occurs when there is an attempt to pop an element from an empty stack, which has no elements to remove. Both conditions can lead to runtime errors and need to be handled to maintain the integrity of the stack operations. Proper checks should be implemented to prevent these situations.
