What is Pushdown Automata in TOC | Definition & Explanation in Urdu/Hindi

In this lecture Pushdown automata has been explained with its definition and tuples. Importance and need of Pushdown automata has also been explained in this lecture. PDA is a way to implement a context-free grammar (CFG) into diagrammatic form. Its implementation is same as DFA, but DFA has finite memory and PDA has infinite memory. It use stack data structure (LIFO). In simple words we can say PDA is = finite state machine + Stack. A PDA can be formally described as a 7-tuple (Q, ∑, S, δ, q0, Z0, F) Q is the finite number of states ∑ is input alphabet q0 is the initial state (q0 ∈ Q) F is a set of accepting states Z0is bottom/initial stack top symbol S is stack symbols δ is the transition function: Q × ∑ × S --- Q × S* What is Pushdown Automata in TOC pushdown Automata in urdu pushdown Automata in hindi pushdown Automata explaination pushdown Automata definition pushdown automata (PDA) in TOC Definition of Pushdown Automata (PDA) #AzComputing #PushDown Automata #PDAIntro
