Card 1Definition of Stack

What is a stack?

Answer

A stack is a linear data structure in which insertion and deletion happen from one end only, called TOP. It follows the LIFO principle, so the last element added is the first one removed.

Card 2स्टैक की परिभाषा

स्टैक क्या है?

Answer

स्टैक एक रैखिक डेटा संरचना है जिसमें सम्मिलन और विलोपन केवल एक छोर से होता है, जिसे TOP कहा जाता है। यह LIFO सिद्धांत का पालन करता है, इसलिए जो अंतिम तत्व जोड़ा जाता है, वही पहला हटाया जाता है।…

Card 3LIFO Principle

Why is stack called a LIFO structure?

Answer

LIFO means Last-In-First-Out. The most recent element inserted at the top is removed first. This is how a pile of plates or books behaves.

Answer

A stack is implemented using the list data type. append() is used for PUSH and pop() is used for POP. No explicit TOP variable is needed because both work at the rightmost end.

Card 8पायथन कार्यान्वयन

पायथन में स्टैक कैसे लागू किया जाता है?

Answer

एक स्टैक को लिस्ट डेटा टाइप का उपयोग करके लागू किया जाता है। append() का उपयोग PUSH के लिए किया जाता है और POP के लिए पॉप () का उपयोग किया जाता है। किसी स्पष्ट TOP चर की आवश्यकता नहीं है क्योंकि दोनों…
