COLeetcode Daily- Day 19: Happy Number
Today’s problem might sound simple, but it’s a solid brain-twister and the best part is we’ll be solving it using two completely different approaches.
✅ Approach 1: Using a HashSet
We keep calculating the sum of squares of digits and store the results in a set.
If we ever hit a number that we’ve already seen before, we know we’re in a cycle and the number is not a happy number
And if we reach 1, it’s a happy number
✅ Approach 2: Fast & Slow Pointer (Cycle Detection)
Instead of using extra space, we use cycle detection method with slow and fast pointers.
slow pointer moves 1 step like this:
slow = findSquare(slow)
fast pointer moves 2 steps like this:
fast = findSquare(findSquare(fast))
If they meet at 1 then that number is Happy number
If they meet at any other point then Not a happy number
Let me know in the comments if you’ve tried this question before.
Hope you liked the concept ❤️

BYTwo sum in Java , leetcode problem
Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target.
You may assume that each input would have exactly one solution, and you may not use the same element twice.
You can return the answer in any order.

AN🌟 Day 3 of my Daily LeetCode Journey!
🚀 1: Two Sum
Today's challenge dove into the world of arrays and dictionaries (hashmaps), focusing on efficient problem-solving (big-o notation).
Key Takeaways:
1. Traverse through the array, keeping track of each element's complement (target - current element).
2. Use a dictionary (hashmap) to store and quickly access the indices of the elements.
3. Check for the complement in the dictionary (hashmap) to find the two numbers that add up to the target.
This solution showcases the efficiency of hashmaps in reducing time complexity, a crucial skill in coding interviews. 🧠💡
Every problem solved is a step forward in our coding journey. Keep pushing those boundaries!
