MinStack Leetcode
Was doing Min stack (Leetcode https://leetcode.com/problems/min-stack/). Was able to figure out using a second stack. But the top voted answer. Oh my gosh. So elegant and clean. Basically, you use a linked list; in every node, keep track of the min value prior to that node. How do people even figure out such stuff? TC 300k #leetcode

Yeah enough practice and exposure to similar questions helps. Instead of linkedlist, stack, vector can also be used. But essentially you keep track of min elements till now
