While calculating xn, the most basic solution is broken down into x ⋅ xn − 1. The new problem is xn − 1, which is similar to the original problem. Therefore, like in original problem, it is further broken down to x ⋅ x ⋅ xn − 2. This is a recursive way of determining the answer to xn.

COMPLETE REFERENCE TO COMPETITIVE PROGRAMMING Competitive Programming. Competitive Programming is a sport, I mean literally. Take any sport, let’s consider cricket for that matter, you walk in to bat for the first time. Swing and a miss, do it couple of times and you’ll eventually hit one over the ropes. Now, consider a programming contest as a game of cricket, metaphorically. 2 DIMENSIONAL PRACTICE PROBLEMS Solve practice problems for 2 Dimensional to test your programming skills.

MINIMUM SPANNING TREE TUTORIALS & NOTES Minimum spanning tree is the spanning tree where the cost is minimum among all the spanning trees. There also can be many minimum spanning trees. Minimum spanning tree has direct application in the design of networks. It is used in algorithms approximating the travelling salesman problem, multi-terminal minimum cut problem and minimum-cost DYNAMIC PROGRAMMING AND BIT MASKING TUTORIALS & NOTES Dynamic Programming and Bit Masking. First thing to make sure before using bitmasks for solving a problem is that it must be having small constraints, as solutions which use bitmasking generally take up exponential time and memory. Let's first try to understand what Bitmask means. Mask in Bitmask means hiding something. BINARY/ N-ARY TREES TUTORIALS & NOTES Binary/ N-ary Trees. A binary tree is a structure comprising nodes, where each node has the following 3 components: As the name suggests, the data element stores any kind of data in the node. The left and right pointers point to binary trees on the left and right side of the node respectively. If a tree is empty, it is represented by a null
