Linked list ek data structure hai jisse
data items nodes ke form mein
organize kiya jata hai, har node ek
value aur next node ka reference
rakhta hai. Yeh ek linear data
structure hai jismein har node apne
successor ko point karta hai, is tarah
se ek chain ban jati hai. Linked list
mein nodes ko dynamically allocate
kiya ja sakta hai, jisse aap data ko as
needed insert aur delete kar sakte
hain.
main aapko aur detail mein samjhata
hoon. Linked list ek aisi data structure
hai jismein data items, ya nodes, ek
sequence mein arrange hote hain. Har
node do cheezen store karta hai:
Value/Data: Ye wo actual data hai jisko
aap linked list mein store karna
chahte
hain. Jaise ki integers, strings, ya koi
bhi custom data type.
Next Node's Reference: Ye pointer hota
hai jo bataata hai ki kis node ke baad
ka node aata hai. Agar ye reference
null hai, toh ye node linked list ki end
ko indicate karta hai.
Yeh structure kuch iss tarah dikhti hai:
lua
Copy code
Node 1 Node 2 Node 3
+------+ +------+ +------+
| 10 | --> | 25 | --> | 7 |
+------+ +------+ +------+
Linked list mein do tarah ki hoti hain:
Singly Linked List: Yahaan har node
apne successor ko point karta hai.
Ismein aap sirf ek direction mein
movement kar sakte hain, yani ki aap
kewal aage ki taraf ja sakte hain.
Doubly Linked List: Har node yahaan
pe apne successor ke saath saath apne
predecessor ko bhi point karta hai.
Isse
aap dono taraf se movement kar sakte
hain, aage aur peeche dono ki taraf.
Linked list ka ek important advantage
hai ki aap asani se data ko insert aur
delete kar sakte hain, kyunki aapko
bas nodes ke pointers ko update karna
hota hai. Lekin, searching karte waqt
aapko linked list ko shuru se traverse
karna pad sakta hai, isse searching
mein thoda time lag sakta hai
compared to arrays jaise data
structures mein.
