Hi, Folks! 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 to think about problems from different angles. There are various ways to solve a problem. If you find one way to solve it, don’t 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: To solve this problem, we can use the concept of backtracking with one base condition. We need to find all possible combinations of characters linked to specific digits in the given input. The base condition will help us stop the function’s execution when necessary. This approach 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 here is to rotate the array by a specified number of positions. We can achieve this by slicing the array according to the specified position and creating a new array by appending the slices in the correct order. This approach solves the problem effectively.
I hope my experience will be helpful to you.
