Hello, Friends! Today, I solved three problems on LeetCode: Letter Combination of a Phone Number, Container with Most Water, and Rotate Array. Solving different problems every day helps us think about problems from different angles. There are various ways to solve a problem. If you find one way to solve it, do not stop there try to optimize the solution further. This will help you find the most efficient way to solve the given problem.
Letter Combination of a Phone Number: In this problem also, we can apply the concept of backtracking with one condition. It asks for a combination of all characters mapped to some specific digits as input. A base condition prevents the function from executing when unnecessary. This method allows us to solve the problem effectively.
Container with Most Water: In this problem, we need to find the maximum area that can be formed. We can traverse the array using two pointers: one starting from the beginning of the array and the other from the end. This method helps us efficiently find the solution.
Rotate Array: The task is to rotate the array for a given number of places. We can easily accomplish this by slicing the array based on the given position and create a new array appending slices in the right order. Thus, it solves the problem properly.
I hope my experience would be helpful to you.
