Sample Coding Interview Problem and Solution

To give you a taste of what to expect in technical interviews, let’s look at a common problem type and how to approach it:

Problem: Two Sum

Given an array of integers and a target sum, return the indices of two numbers such that they add up to the target.

For example:

Input: nums = [2, 7, 11, 15], target = 9
Output: [0, 1] (because nums[0] + nums[1] = 2 + 7 = 9)

Solution Approach:

A naive approach would be to use nested loops to check each pair of numbers, but this has O(n²) time complexity. A more efficient approach uses a hash map:

def two_sum(nums, target):
    # Create a dictionary to store numbers we've seen and their indices
    seen = {}
    
    # Check each number in the array
    for i, num in enumerate(nums):
        # Calculate the complement (the number we need to find)
        complement = target - num
        
        # If the complement is in our dictionary, we found a solution
        if complement in seen:
            return [seen[complement], i]
        
        # Otherwise, add the current number to our dictionary
        seen[num] = i
    
    # If no solution is found
    return None

Explanation:

This solution has:

  • Time Complexity: O(n) as we only need to traverse the array once
  • Space Complexity: O(n) for storing the hash map

During an interview, you would not only need to code this solution but also explain your thought process, analyze the time and space complexity, and possibly discuss alternative approaches or optimizations.
