15 Sample Questions with Solutions

Advanced Aptitude (Questions 1-4)

Q1. If log₂(log₃(log₄x)) = 0, what is the value of x?

• a) 64
• b) 81
• c) 256
• d) 4

Solution: log₂(log₃(log₄x)) = 0 → log₃(log₄x) = 2⁰ = 1 → log₄x = 3¹ = 3 → x = 4³ = 64

---

Q2. A and B can complete a work in 12 days. B and C in 15 days. C and A in 20 days. How long will A alone take?

• a) 20 days
• b) 25 days
• c) 30 days
• d) 35 days

Solution: 2(A+B+C) = 1/12 + 1/15 + 1/20 = (5+4+3)/60 = 12/60 = 1/5. So A+B+C = 1/10. A = (A+B+C) - (B+C) = 1/10 - 1/15 = 1/30. Days = 30.

---

Q3. The sum of the first n odd natural numbers is:

• a) n(n+1)
• b) n²
• c) 2n²
• d) n(n+1)/2

Explanation: 1 + 3 + 5 + ... + (2n-1) = n²

---

Q4. A man rows upstream at 8 km/hr and downstream at 12 km/hr. What is the speed of the stream?

• a) 2 km/hr
• b) 4 km/hr
• c) 6 km/hr
• d) 8 km/hr

Solution: Speed of stream = (Downstream - Upstream)/2 = (12-8)/2 = 2 km/hr

---

Advanced Logical Reasoning (Questions 5-7)

Q5. In a code language, '123' means 'bright little boy', '145' means 'tall big boy', and '637' means 'beautiful little flower'. Which digit represents 'bright'?

• a) 1
• b) 2
• c) 3
• d) 4

Solution: From 123 and 145: '1' = 'boy'. From 123 and 637: '3' = 'little'. So '2' = 'bright'.

---

Q6. Six friends A, B, C, D, E, and F are sitting in a circle facing the center. A is between D and F. C is between E and B. E is not next to D. Who is between A and C?

• a) B
• b) D
• c) E
• d) F

Explanation: Arrangement (clockwise): D-A-F-?-E-C-B. Since E is not next to D, the arrangement is D-A-F-B-E-C. So D is between C and A (going the other way).

---

Q7. Complete the pattern: 1, 2, 6, 24, 120, ?

• a) 600
• b) 720
• c) 840
• d) 5040

Solution: Pattern: ×2, ×3, ×4, ×5, ×6 → 120 × 6 = 720 (Factorials: 1!, 2!, 3!, 4!, 5!, 6!)

---

Programming Concepts (Questions 8-10)

Q8. What is the time complexity of the following code?

for(int i = 0; i < n; i++)
    for(int j = 0; j < i; j++)
        printf("*");

• a) O(n)
• b) O(n²)
• c) O(n log n)
• d) O(n³)

Explanation: Inner loop runs 0 + 1 + 2 + ... + (n-1) = n(n-1)/2 = O(n²)

---

Q9. Which data structure is best for implementing LRU (Least Recently Used) cache?

• a) Array
• b) Stack
• c) Queue
• d) Hash Map + Doubly Linked List

---

Q10. What is the output of the following Java code?

class Test {
    public static void main(String[] args) {
        String s1 = new String("Hello");
        String s2 = new String("Hello");
        System.out.println(s1 == s2);
        System.out.println(s1.equals(s2));
    }
}

• a) true true
• b) false true
• c) true false
• d) false false

Explanation: '==' compares references (different objects), equals() compares content.

---

Data Structures & Algorithms (Questions 11-12)

Q11. Which algorithm is most efficient for finding the shortest path in a weighted graph with negative edges?

• a) Dijkstra's
• b) Bellman-Ford
• c) Floyd-Warshall
• d) BFS

Explanation: Bellman-Ford handles negative edge weights, unlike Dijkstra's.

---

Q12. What is the best case time complexity of QuickSort?

• a) O(n)
• b) O(n log n)
• c) O(n²)
• d) O(log n)

Advanced Coding Questions (Questions 13-15)

Q13. Write a program to find the longest palindromic substring.

Solution:

def longest_palindrome(s):
    if not s:
        return ""
    
    start, max_len = 0, 1
    
    for i in range(len(s)):
        # Odd length palindromes
        l, r = i, i
        while l >= 0 and r < len(s) and s[l] == s[r]:
            if r - l + 1 > max_len:
                start = l
                max_len = r - l + 1
            l -= 1
            r += 1
        
        # Even length palindromes
        l, r = i, i + 1
        while l >= 0 and r < len(s) and s[l] == s[r]:
            if r - l + 1 > max_len:
                start = l
                max_len = r - l + 1
            l -= 1
            r += 1
    
    return s[start:start + max_len]

s = input()
print(longest_palindrome(s))

Solution:

#include<stdio.h>

int max_subarray_sum(int arr[], int n) {
    int max_so_far = arr[0];
    int max_ending_here = arr[0];
    
    for(int i = 1; i < n; i++) {
        if(max_ending_here + arr[i] > arr[i])
            max_ending_here = max_ending_here + arr[i];
        else
            max_ending_here = arr[i];
        
        if(max_ending_here > max_so_far)
            max_so_far = max_ending_here;
    }
    
    return max_so_far;
}

int main() {
    int n;
    scanf("%d", &n);
    int arr[n];
    for(int i = 0; i < n; i++)
        scanf("%d", &arr[i]);
    printf("%d", max_subarray_sum(arr, n));
    return 0;
}

class LinkedList {
    Node head;
    
    boolean hasCycle() {
        Node slow = head, fast = head;
        while(fast != null && fast.next != null) {
            slow = slow.next;
            fast = fast.next.next;
            if(slow == fast)
                return true;
        }
