2976. Minimum Cost to Convert String I | Leetcode Daily (POTD) 27 July 2024 | Java | Hindi | graphs

"2976. Minimum Cost to Convert String I" is a thought-provoking medium-level problem and the daily challenge (POTD) for 27 July 2024 on LeetCode. The solution presented in the video is coded in Java, but the approach is explained using a dry-run on a blackboard. This method makes the video accessible and beneficial for individuals with different programming backgrounds, as it focuses on the underlying logic rather than language-specific details.

**Intuition:**
This problem can be transformed into finding the minimum path between all nodes in a graph, making it suitable for the Floyd-Warshall algorithm. For those familiar with graph theory, this algorithm provides a systematic way to compute the shortest paths between all pairs of nodes, allowing us to determine the minimum cost required to convert the string.

By utilizing the Floyd-Warshall algorithm, we can effectively break down the problem into manageable parts, focusing on computing and comparing path costs. This approach highlights the power of graph algorithms in solving complex problems by leveraging their ability to find optimal paths, thereby offering an elegant and efficient solution.

The way you explain the concept is Marvellous🎉.
Ma'am i am watching your each video and basically I am learning from you so thank you ma'am 🥰

Good explanation. But, I think we don't require that for loop which makes the diagonal or same value char zero. As anyway we are skipping it in final calculation. Also, instead of >= that condition should be == Integer.MAX_VALUE
