Pattern problem

One Pattern

Print in the output the exact pattern provided below 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1


public class PatternPrinter {

    public static void main(String[] args) {

        int rows = 5; // Number of lines


        for (int i = 1; i <= rows; i++) {

            for (int j = 1; j <= i; j++) {

                System.out.print("1 ");

            }

            System.out.println(); // Move to next line

        }

    }

}


Number Pattern

Print in the output the exact pattern provided below 1 2 3 4 5 1 2 3 4 1 2 3 1 2 1



public class ReversePattern { public static void main(String[] args) { int rows = 5; // Number of rows for (int i = rows; i >= 1; i--) { for (int j = 1; j <= i; j++) { System.out.print("1 "); } System.out.println(); // Move to next line } } }



V Pattern

Print in the output the exact pattern provided below 1 1 12 21 123 321 1234 4321 1234554321



public class VNumberPattern { public static void main(String[] args) { int n = 5; // number of rows for (int i = 1; i <= n; i++) { // Print increasing numbers from 1 to i for (int j = 1; j <= i; j++) { System.out.print(j); } // Print spaces: 2*(n - i) spaces for (int j = 1; j <= 2 * (n - i); j++) { System.out.print(" "); } // Print decreasing numbers from i to 1 for (int j = i; j >= 1; j--) { System.out.print(j); } System.out.println(); // move to next line } } }

Two Sum II - Input Array Is Sorted

 Given a 1-indexed array of integers numbers that is already sorted in non-decreasing order , find two numbers such that they add up to a specific target number. Let these two numbers be numbers[index1] and numbers[index2] where 1 <= index1 < index2 <= numbers.length. Return the indices of the two numbers, index1 and index2, added by one as an integer array [index1, index2] of length 2. The tests are generated such that there is exactly one solution. You may not use the same element twice. Your solution must use only constant extra space .   Example 1: Input: numbers = [2,7,11,15], target = 9 Output: [1,2] Explanation: The sum of 2 and 7 is 9. Therefore, index1 = 1, index2 = 2. We return [1, 2]. Example 2: Input: numbers = [2,3,4], target = 6 Output: [1,3] Explanation: The sum of 2 and 4 is 6. Therefore index1 = 1, index2 = 3. We return [1, 3]. Example 3: Input: numbers = [-1,0], target = -1 Output: [1,2] Explanation: The sum of -1 and 0 is -1. Therefore index1 = 1,...

Comparable Vs. Comparator in Java

  In Java , Comparable and Comparator both are interfaces used to sort objects. Comparable It defines  natural ordering  within a class. It is implemented  inside  the class being sorted. It uses the compareTo() method. It allows sorting  by one one . Comparable provides a  single sorting sequence . In other words, we can sort the collection on the basis of a single element such as id, name, and price. Comparable  affects the original class , i.e., the actual class is modified. Comparable is present in  java.lang  package. We can sort the list elements of Comparable type by  Collections.sort(List)  method. Only one compareTo() method can be implemented, restricting flexibility. Comparator It defines  custom sorting logic It is implemented  in a separate class  or using lambda expressions . It uses the compare() method. It allows sorting  by multiple criteria . The Comparator provides  multiple sorting...

Increasing Triplet Subsequence

 Given an integer array nums, return true if there exists a triple of indices (i, j, k) such that i < j < k and nums[i] < nums[j] < nums[k]. If no such indices exists, return false.   Example 1: Input: nums = [1,2,3,4,5] Output: true Explanation: Any triplet where i < j < k is valid. Example 2: Input: nums = [5,4,3,2,1] Output: false Explanation: No triplet exists. Example 3: Input: nums = [2,1,5,0,4,6] Output: true Explanation: The triplet (3, 4, 5) is valid because nums[3] == 0 < nums[4] == 4 < nums[5] == 6. Brute Force : Failed for some testcase class Solution {     public boolean increasingTriplet ( int [] nums ) {         int n = nums . length ;         int i = 0 ;         int j =i+ 1 ;         int k =j+ 1 ;         while (i <n && j<n && k<n)         {         if (nums...
