In this video, we break down LeetCode 1773 step by step and solve it using an easy C++ approach.
The problem asks us to count how many items satisfy a given rule based on:
type
color
or name
Weโll learn how to:
โ๏ธ Traverse a 2D vector
โ๏ธ Compare strings efficiently
โ๏ธ Use conditions smartly
โ๏ธ Write clean and optimized C++ code
๐น Solution Strategy:
We iterate through every item and compare the required field with the given rule value.
If it matches, we increase the answer count.
๐ Why this problem is useful:
Improves array handling
Strengthens conditional logic
Great practice for beginners
Helps build coding interview confidence
โก Complexity:
Time: O(n)
Space: O(1)
This tutorial is perfect for students, beginners, and anyone practicing Data Structures & Algorithms.
๐ฏ Watch till the end for a clear explanation and easy-to-understand code walkthrough.
