Check if a String is Palindrome in Java

Built a Java program to classify user input 💻 Used Scanner for taking input from user. Extracted character using charAt(0). Checked if input is alphabet, digit, or special character. Handled both uppercase and lowercase cases. Applied if-else logic effectively. Improved understanding of Java fundamentals. Practiced clean and structured coding. Strengthening logic building step by step 🚀 Consistency leads to better problem-solving skills 🔥 #Java #JavaProgramming #CodingJourney #LearnToCode #StudentDeveloper #ProgrammingBasics #LogicBuilding #TechSkills #VSCode #100DaysOfCode

Problem Solved Today 💡 Today I solved a basic problem on Arrays, and it taught me something important. 📌 Problem: Find the largest element in an array 📌 Approach: Used a simple loop to compare elements 📌 Language: C / Java 👉 What I learned: Instead of jumping to complex solutions, sometimes simple logic works best. Coding is not about writing big code, it’s about clear thinking. Small steps every day = big improvement over time 🚀 #CodingJourney #ProblemSolving #Java #CProgramming #DataStructures #LearnToCode #FutureEngineer

Entry-level Algorithm Challenge: Array Manipulation in Java. Today I tackled a foundational exercise: reading a list of numbers and filtering out only the negative values. It was a great opportunity to reinforce some core Java concepts: 1. Flow control with do-while loop: Ensuring valid input within a specific range. 2. Simplified iteration with for-each loop: Improving code readability. 3. Handling flags (boolean signals): Providing clear, user-friendly feedback.

Java hidden feature 🔥 I want to tell you a feature that not many people know about, you can use labels to control nested loops. For example, if you are using 2 loops, you can jump to the first one, it is very logical. For this, you give a name to the loops, you can give it any name you want, I gave outer, then you put : and then put loop. Which other languages have such a feature, if there is one in other programming, please share it. #Java #SpringBoot #BackendDevelopment #JavaDeveloper #SoftwareEngineer #Coding #Loop

100 Days of Coding Challenge – Day 17 📌 Problem: String Compression 💻 Language: Java 🧠 Concept Used: Two Pointers + In-place Array Manipulation 🔍 Platform: LeetCode Today’s challenge was to compress a character array in-place by replacing consecutive repeating characters with the character followed by its count. Example: Input: ["a","a","b","b","c","c","c"] Output: ["a","2","b","2","c","3"] Approach: ✔ Use two pointers — one for reading characters and one for writing compressed output ✔ Count consecutive repeating characters ✔ Write the character once and append the count if it is greater than 1 ✔ Modify the array directly without creating extra space Time Complexity: O(n) Space Complexity: O(1) 🔗 Problem Link: https://lnkd.in/eeeWBA4X 🔗 Code: https://lnkd.in/enj4Qcy9 #100DaysOfCode #Day17 #Java #DSA #LeetCode #Strings #TwoPointers #ProblemSolving #CodingJourney

🚀 Turning Logic into Creativity with Java! I recently worked on an interesting Java pattern programming project where I created alphabet letters using the "*" symbol. Using loops and conditional statements in Java, I connected multiple "*" characters to form different alphabet patterns. This exercise helped me strengthen my logical thinking, pattern design, and control structure concepts in Java. Pattern programming is a great way to improve problem-solving skills and understand how programming logic works step by step. Excited to keep learning and building more creative programs! 💻✨ G.R NARENDRA REDDY Global Quest Technologies #Java #PatternProgramming #CodingPractice #ProblemSolving #LearningJourney

100 Days of Coding Challenge – Day 18 📌 Problem: Is Subsequence 💻 Language: Java 🧠 Concept Used: Two Pointer Technique 🔍 Platform: LeetCode Today’s challenge was to determine whether a string s is a subsequence of another string t. A subsequence means the characters appear in the same order, but not necessarily consecutively. Approach: ✔ Use two pointers to traverse both strings ✔ If characters match, move both pointers ✔ Otherwise, move the pointer of the second string ✔ If all characters of s are matched, it is a valid subsequence ✔ Time Complexity: O(n) ✔ Space Complexity: O(1) This problem reinforced how powerful the two-pointer technique can be for efficient string traversal. 🔗 Problem Link: https://lnkd.in/g_43jvhm 🔗 Code: https://lnkd.in/gG_7d2BC #100DaysOfCode #Day18 #Java #DSA #LeetCode #TwoPointers #Strings #ProblemSolving #CodingJourney

While solving a DSA problem on LeetCode, I noticed the solution used StringBuilder instead of a normal String in Java. At first I thought — why not just use String? 🤔 While exploring this, I learned that every time we modify a String, Java creates a new object in memory. The old objects become unused, which are called garbage values and later cleaned by the garbage collector. A small doubt while solving one question helped me understand how memory actually works in Java 💡 #Java #DSA #LearningInPublic #Programming #LeetCode

🚀 DSA in Java – Day 76 ✅ Today I solved the “Check if Binary String Has at Most One Segment of Ones” problem on LeetCode. 💡 Problem Idea: Given a binary string, we need to check whether there is at most one continuous segment of '1's in the string. 🧠 Approach: Traverse the string using a loop. Count how many segments of '1' appear. If the count becomes greater than 1, return false. Otherwise return true. ⚡ Key Concepts Practiced: String traversal While loop Character comparison Logical conditions Consistency in solving problems every day is helping me strengthen my problem-solving and logical thinking skills in Java. #DSA #Java #LeetCode #ProblemSolving #CodingJourney #WomenInTech #100DaysOfCode
