🧒🍬 Beginner-Friendly Guide to Solving "Distribute Candies Among Children" | LeetCode 135 Explained (C++ | JavaScript | Python)

  • LeetCode 135 - Candy problem involves distributing candies to children based on their ratings in a line, following certain rules.
  • The problem requires each child to receive at least one candy and a child with a higher rating than adjacent child gets more.
  • Two strategies discussed in the guide are a naive two-pass greedy approach and an optimized greedy algorithm.
  • The optimized greedy solution reduces space complexity from O(n) to O(1) by tracking peaks, valleys, and previous candies given.
  • Code implementations provided in C++, JavaScript, and Python demonstrate the optimized approach.
  • Test cases cover various scenarios to validate the correctness of the implemented solutions.
  • Key takeaways include understanding the intuition behind both approaches and the significance of optimizing space for large datasets.
  • Overall, mastering this problem helps in grasping greedy algorithms and efficient space utilization in coding interviews and DSA practice.
