In this video, we’ll solve LeetCode Problem #1 — Two Sum, one of the most popular DSA array problems asked in coding interviews (Amazon, Microsoft, TCS, etc.).

We’ll discuss step-by-step:
✅ Problem understanding and dry run
✅ Brute-force solution using nested loops
✅ Logic building for pair-sum problems
✅ How to implement Two Sum in Python
✅ Time & Space complexity

💡 Concepts Covered:

Array Traversal

Nested Loops

Index Tracking

Condition Checking

🧾 Code Used in Video
class Solution:
def twoSum(self, nums, target):
n = len(nums)
for i in range(n):
for j in range(i+1, n):
if nums[i] + nums[j] == target:
return [i, j]

Example
nums = [2, 7, 11, 15]
target = 9
sol = Solution()
print(sol.twoSum(nums, target)) # Output: [0, 1]
