DATA TYPES & BASICS

x = 10 # int
y = 3.14 # float
s = 'hello' # string
b = True # boolean
l = [1,2,3] # list (mutable)
t = (1,2,3) # tuple (immutable)
d = {'a': 1} # dictionary
st = {1,2,3} # set (unique values)

====================================
STRINGS โ€” Most Asked!

s = 'Hello World'
s.upper() # 'HELLO WORLD'
s.lower() # 'hello world'
s.split(' ') # ['Hello', 'World']
s.replace('o','0') # 'Hell0 W0rld'
s.strip() # remove whitespace
len(s) # 11
s[0:5] # 'Hello' (slicing)
s[::-1] # reverse string!
f'Name: {s}' # f-string formatting

====================================
LIST OPERATIONS

l = [3, 1, 4, 1, 5]
l.append(9) # add to end
l.insert(0, 7) # insert at index 0
l.remove(1) # remove first '1'
l.pop() # remove last element
l.sort() # sort in place
sorted(l) # returns new sorted list
l.reverse() # reverse in place
len(l) # length of list
sum(l) # sum of all elements
max(l), min(l) # max and min value

====================================
LIST COMPREHENSION โ€” Interviewers Love!

squares = [x**2 for x in range(10)]
# [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

d.get('city', 'N/A') # safe get
d.keys() # all keys
d.values() # all values
d.items() # key-value pairs
d.update({'city': 'Delhi'}) # add/update

====================================
FUNCTIONS & LAMBDA

def add(a, b):
return a + b

# Lambda (one-line function)
square = lambda x: x**2
square(5) # 25

# *args and **kwargs
def greet(*names):
for name in names:
print(f'Hi {name}')

====================================
MUST-KNOW PYTHON CONCEPTS:

List vs Tuple -> mutable vs immutable

Anagram check -> sort both or HashMap
Longest common prefix -> vertical scan
Count vowels/consonants -> loop + set
String reversal -> s[::-1] in Python

====================================
LINKED LIST โ€” Very Frequently Asked!

Reverse a linked list -> 3 pointer trick
Detect cycle -> Floyd's algo (slow/fast)
Find middle node -> slow/fast pointers
Merge 2 sorted lists -> compare & merge
Remove Nth node from end -> two pass

====================================
STACK & QUEUE

Stack: LIFO โ€” use for:
-> Valid parentheses check
-> Next Greater Element
-> Undo/Redo operations

Queue: FIFO โ€” use for:
-> BFS (level order traversal)
-> Sliding window maximum

====================================
TREES โ€” 30% of Interview Questions!

Inorder: Left -> Root -> Right
Preorder: Root -> Left -> Right
Postorder: Left -> Right -> Root

Level Order -> use Queue (BFS)
Height of tree -> recursion
Check BST -> inorder should be sorted
LCA of two nodes -> recursive approach

====================================
SORTING ALGORITHMS

Bubble Sort -> O(nยฒ) | Simple
Selection Sort -> O(nยฒ) | Simple
Insertion Sort -> O(nยฒ) | Best for small
Merge Sort -> O(nlogn) | Stable sort
Quick Sort -> O(nlogn) | In-place

For interviews: Know Merge Sort well!

====================================
SEARCHING

Linear Search -> O(n) | Unsorted array
Binary Search -> O(logn) | Sorted array only

Binary Search template:
low, high = 0, len(arr)-1
while low <= high:
mid = (low + high) // 2
if arr[mid] == target: return mid
elif arr[mid] < target: low = mid+1
else: high = mid-1

====================================
TIME COMPLEXITY QUICK REFERENCE:

O(1) -> Constant | Array index access
O(logn) -> Log | Binary search
O(n) -> Linear | Single loop
O(nlogn) -> Linearithmic | Merge sort
O(nยฒ) -> Quadratic | Nested loops

====================================
ARRAYS - Most Basic, Most Asked!

Two Sum -> HashMap O(n)
Find max/min -> linear scan O(n)
Reverse array -> two pointers O(n)
Find duplicates -> HashSet O(n)
Rotate by k -> reverse technique O(n)
Subarray sum -> sliding window O(n)
Merge sorted arrays -> two pointer O(n+m)

====================================
STRINGS

Palindrome check -> two pointers O(n)
Anagram check -> sort or HashMap O(n)
Longest substring no repeat -> sliding window
String reversal -> s[::-1] in Python
Count char frequency -> HashMap O(n)

====================================
LINKED LIST - Very Frequently Asked!

Reverse linked list -> 3 pointer trick O(n)
Detect cycle -> Floyd's slow/fast O(n)
Find middle -> slow/fast pointers O(n)
Merge 2 sorted lists -> compare & link O(n)
Remove Nth from end -> two pass O(n)

====================================
STACK & QUEUE

Stack (LIFO) - use for:
-> Valid parentheses {[()]}
-> Next Greater Element
-> Undo/Redo operations

Queue (FIFO) - use for:
-> BFS (level order tree traversal)
-> Sliding window maximum

====================================
TREES - 30% of Interview Questions!

Inorder: Left Root Right
Preorder: Root Left Right
Postorder: Left Right Root
Level Order: BFS using Queue

Height of tree -> recursion O(n)
Check BST valid -> inorder sorted check
Lowest Common Ancestor -> recursive O(n)
Path sum root to leaf -> DFS O(n)

====================================
GRAPHS

BFS -> Queue, shortest path unweighted
DFS -> Stack/Recursion, path finding
Detect cycle undirected -> Union Find
Detect cycle directed -> DFS + visited
Topological Sort -> Kahn's algo (BFS)

====================================
DYNAMIC PROGRAMMING

Fibonacci -> memoization O(n)
0/1 Knapsack -> 2D DP O(n*W)
Longest Common Subsequence -> 2D DP
Coin Change -> bottom-up DP O(n*amount)
Climb Stairs -> DP same as Fibonacci

====================================
TIME COMPLEXITY QUICK REFERENCE:

O(1) Constant | Array index
O(logn) Log | Binary search
O(n) Linear | Single loop
O(nlogn) Linearithmic | Merge sort
O(n2) Quadratic | Nested loops
O(2n) Exponential | Recursion tree
