LeetCode 1979 Explained | GCD of Array | Easy DSA Problem for Beginners

In this video, we solve LeetCode 1979: Find Greatest Common Divisor of Array. This is an easy problem, but it teaches very important DSA concepts: array traversal, finding minimum and maximum elements, GCD, divisors, and the Euclidean Algorithm. We first understand the problem, then build the logic step by step, write the algorithm, discuss time and space complexity, code the solution, dry run examples, and finally look at common mistakes. Topics covered: Array traversal Minimum and maximum in an array Greatest Common Divisor Euclidean Algorithm Time and space complexity Keep learning DSA one problem at a time.
