From 0 to 1 Data Structures & Algorithms in Java - Find The Minimum Element In A Stack In Constant Time

The video tutorial explains how to find the minimum element in a stack in constant time using a dual stack approach. It begins by discussing the limitations of traditional methods, which require iterating through the stack, and introduces a more efficient solution using two stacks: one for the actual elements and another for tracking the minimum elements. The tutorial includes a visual demonstration and a detailed code implementation, ensuring that the minimum element can be accessed in constant time regardless of stack operations.
