Sample Flipkart Online Assessment Questions

Question 1: Array Problem

Q: Given an array of product prices, find the maximum profit from buying and selling (similar to stock problem).

Problem: Find the maximum profit from buying and selling products, where you can make at most one transaction.

Solution:

public int maxProfit(int[] prices) {
    if (prices.length == 0) return 0;

    int minPrice = prices[0];
    int maxProfit = 0;

    for (int i = 1; i < prices.length; i++) {
        if (prices[i] < minPrice) {
            minPrice = prices[i];
        } else {
            maxProfit = Math.max(maxProfit, prices[i] - minPrice);
        }
    }

    return maxProfit;
}

Time Complexity: O(n) Space Complexity: O(1)

Question 2: Tree Problem

Q: Given a binary tree representing product categories, find the maximum depth.

Solution:

class TreeNode {
    int val;
    TreeNode left, right;
}

public int maxDepth(TreeNode root) {
    if (root == null) return 0;

    int leftDepth = maxDepth(root.left);
    int rightDepth = maxDepth(root.right);

    return 1 + Math.max(leftDepth, rightDepth);
}

Time Complexity: O(n) Space Complexity: O(h) where h is height

Flipkart Online Assessment Tips

Optimal Solutions Matter

Flipkart OA evaluates not just correctness but also optimality. Focus on time and space complexity. O(n²) solutions may not pass all test cases even if correct.

General Tips

1. Read Problems Carefully: Understand requirements and constraints
2. Plan Before Coding: Outline approach and algorithm
3. Handle Edge Cases: Consider empty arrays, single elements, etc.
4. Test Your Code: Verify with sample inputs before submitting
5. Optimize Solutions: Aim for optimal time/space complexity
6. Manage Time: Don’t spend too long on one problem
