Stack and Queue is LIFO

Detailed explanation-1: -The primary difference between Stack and Queue Data Structures is that Stack follows LIFO while Queue follows FIFO data structure type. LIFO refers to Last In First Out. It means that when we put data in a Stack, it processes the last entry first. Conversely, FIFO refers to First In First Out.
Detailed explanation-2: -A stack follows a LIFO (Last In First Out) order, whereas a queue follows a FIFO (First In First Out) order for storing the elements. A stack uses one end known as a top for insertion and deletion whereas a queue uses two ends front and rear for insertion and deletion.
Detailed explanation-3: -Queue: First In First Out (FIFO): The first object into a queue is the first object to leave the queue, used by a queue. Stack: First In Last Out (FILO): The first object or item in a stack is the last object or item to leave the stack.
Detailed explanation-4: -The operations of a queue make it a first-in-first-out (FIFO) data structure. In a FIFO data structure, the first element added to the queue will be the first one to be removed.
Detailed explanation-5: -Queues use two ends of the structure; stacks use only one.
