42nd day of my CP journey

This is the 42nd day of the Competitive programming journey. I am happy to have started this. Through this journey I have discovered many platforms and their workings. In this journey I had come accross working with Strings, Arrays and many more data structures. Today I have solved questions from Leetcode.

Concepts involved :-

Combination Sum 2 - Backtracking, conditional statements, loops.
Power Sum - Mathematical operations.

First question I did for today is "Combination sum 2". With this question, I worked with concepts like backtracking, loops and if-else statements.

Secondly I did a question names "Power Sum". This question felt very simple with a ideal time complexity.
