🚀 Coding Interview Questions with Answers (Part :-1)

1️⃣8️⃣9️⃣ Check if Two Strings are Anagrams
👉 Same characters, same frequency, different order.

python
s1, s2 = "listen", "silent"
print(sorted(s1) == sorted(s2))

⏱ O(n log n)

1️⃣9️⃣0️⃣ Factorial of a Number
👉 Product of all integers from 1 to n.

python
def factorial(n):
result = 1
for i in range(1, n+1):
result *= i
return result

⏱ O(n)

1️⃣9️⃣1️⃣ Check if a Number is Prime
👉 Divisible only by 1 and itself.

python
def is_prime(n):
if n < 2: return False
for i in range(2, int(n**0.5)+1):
if n % i == 0: return False
return True

⏱ O(√n)

1️⃣9️⃣2️⃣ Fibonacci Sequence
👉 Sum of the two preceding numbers.

python
def fibonacci(n):
seq = [0, 1]
while len(seq) < n:
seq.append(seq[-1]+seq[-2])
return seq[:n]

⏱ O(n)

1️⃣9️⃣3️⃣ GCD of Two Numbers
👉 Euclidean algorithm.

python
def gcd(a, b):
while b:
a, b = b, a % b
return a

⏱ O(log(min(a,b)))

1️⃣9️⃣4️⃣ Frequency of Elements
👉 Count occurrences using Counter.

python
from collections import Counter
print(Counter([1,2,2,3,3,3]))

⏱ O(n)

1️⃣9️⃣5️⃣ Rotate Array by K Positions
👉 Slice and swap.

python
def rotate(arr, k):
k = k % len(arr)
return arr[-k:] + arr[:-k]

⏱ O(n)

🚀 Coding Interview Questions with Answers (Part:-2)

1️⃣9️⃣6️⃣ Find All Pairs with a Given Sum
👉 Use a set to track complements while scanning.

python
def find_pairs(arr, target):
seen, pairs = set(), []
for num in arr:
complement = target - num
if complement in seen:
pairs.append((complement, num))
seen.add(num)
return pairs

print(find_pairs([2,4,3,7,1,5], 7))

⏱ O(n)

1️⃣9️⃣7️⃣ Check if an Array is Sorted
👉 Compare each element with the next one.

python
def is_sorted(arr):
return all(arr[i] <= arr[i+1] for i in range(len(arr)-1))

print(is_sorted([1,2,3,4,5]))

⏱ O(n)

1️⃣9️⃣8️⃣ Find the Intersection of Two Arrays
👉 Use set intersection to find common elements.

python
a = [1,2,3,4]
b = [3,4,5,6]
print(list(set(a) & set(b)))

⏱ O(n+m)

1️⃣9️⃣9️⃣ Count Vowels in a String
👉 Loop through and check membership in a vowel set.

python
def count_vowels(s):
return sum(1 for ch in s.lower() if ch in "aeiou")

print(count_vowels("Hello World"))

⏱ O(n)

2️⃣0️⃣0️⃣ Check if a Number is a Power of Two
👉 A power of two has exactly one bit set — use bitwise AND trick.

python
def is_power_of_two(n):
return n > 0 and (n & (n-1)) == 0

print(is_power_of_two(16))

⏱ O(1)

2️⃣0️⃣1️⃣ Flatten a Nested List
👉 Recursively unpack nested lists into a single flat list.

python
def flatten(lst):
result = []
for item in lst:
if isinstance(item, list):
result.extend(flatten(item))
else:
result.append(item)
return result

print(flatten([1, [2, 3, [4, 5]], 6]))

⏱ O(n)

2️⃣0️⃣2️⃣ Find the First Non-Repeating Character
👉 Use a frequency count, then find the first with count 1.

python
from collections import Counter

def first_unique(s):
freq = Counter(s)
for ch in s:
if freq[ch] == 1:
return ch
return None

print(first_unique("swiss"))

⏱ O(n)

🚀 Coding Interview Questions with Answers (Part 3)

2️⃣0️⃣3️⃣ Find the Union of Two Arrays
👉 Combine both arrays and remove duplicates.

python
a = [1,2,3,4]
b = [3,4,5,6]
print(list(set(a) | set(b)))

⏱ O(n+m)

2️⃣0️⃣4️⃣ Check if a String Contains Only Digits
👉 Use the built-in isdigit() method.

python
s = "12345"
print(s.isdigit())

⏱ O(n)

2️⃣0️⃣5️⃣ Find the Sum of Digits of a Number
👉 Repeatedly extract the last digit and add it up.

python
def sum_of_digits(n):
total = 0
while n > 0:
total += n % 10
n //= 10
return total

print(sum_of_digits(12345))

⏱ O(log n)

2️⃣0️⃣6️⃣ Reverse an Integer
👉 Convert to string, reverse, convert back — or use math.

python
def reverse_int(n):
sign = -1 if n < 0 else 1
n = abs(n)
reversed_num = int(str(n)[::-1])
return sign * reversed_num

print(reverse_int(-12345))

⏱ O(log n)

2️⃣0️⃣7️⃣ Check if a String is a Subsequence of Another
👉 Use two pointers to compare characters in order.

python
def is_subsequence(s, t):

perms = ["".join(p) for p in permutations(s)]
print(perms)

⏱ O(n!)
