When it comes to processing strings containing parentheses, such as mathematical expressions or structured data, determining the maximum depth of these parentheses can be a useful task. In this blog, we’ll delve into a Java solution that accomplishes this task efficiently. his Solution class contains a method maxDepth(String s) that takes a string s as…

## 205. Isomorphic Strings

Isomorphic strings are two strings where characters at the same index in both strings can be replaced to make the strings equal. In other words, if we can replace all occurrences of one character in the first string with another character and obtain the second string, and vice versa, then the strings are isomorphic. In…

## 1750. Minimum Length of String After Deleting Similar Ends

The problem statement provides a string s and requires us to find the minimum length of a palindrome that can be obtained by removing characters from the ends of the string. This essentially means finding the length of the longest palindrome prefix and suffix of the string. Approach and Solution The given Java solution provides…

## 1642. Furthest Building You Can Reach

Understanding the Problem: Imagine traversing a series of buildings, each with its own height. We’re equipped with a limited supply of bricks and ladders, and our goal is to reach as far as possible while conserving resources. The furthest building problem challenges us to determine the maximum distance we can travel given the heights of…

## 1481. Least Number of Unique Integers after K Removals

Understanding the Problem: Before we dive into the code, let’s take a moment to understand the problem at hand. We’re given an array of integers and a value k, representing the maximum number of elements we can remove from the array. Our goal is to determine the least number of unique integers remaining in the…

## 56. Merge Intervals

Understanding the Problem Given a collection of intervals represented as an array of pairs [start, end], the task is to merge overlapping intervals and return a new array of non-overlapping intervals. Approach To merge intervals efficiently, we can follow these steps: Create a class Interval to represent each interval with start and end attributes. Implement…

## 1463. Cherry Pickup II

We are given a grid where each cell represents the number of cherries available. Two robots start at the top-left corner of the grid and must traverse down to the bottom-right corner. Each robot can move only in three directions: down, right, or diagonally down-right. However, the robots cannot occupy the same cell at the…

## 279. Perfect Squares

The Perfect Squares problem is a classic dynamic programming challenge where the goal is to find the minimum number of perfect square numbers (numbers that can be expressed as the square of an integer) that sum up to a given positive integer ‘n’. In this blog, we’ll explore the problem, understand its intuition, and implement…
