We just launched 𝐋𝐞𝐞𝐭𝐂𝐨𝐝𝐞 𝐕𝐢𝐬𝐮𝐚𝐥𝐢𝐳𝐞𝐫, a free tool that shows what your code is actually doing, line by line. The problem: when a LeetCode solution fails, you're left staring at code and guessing what line 14 did. Print statements only get you so far, and a recursion call stack is basically invisible. ▪️ Step through code, line by line, forwards and backwards. ▪️ Watch data structures such as arrays, grids, trees, linked lists and graphs come alive. ▪️ Supports Python, C++ and Java.
