Rotate Array

 The input specifies there is 1 test case.

For the first test case, the size of the array is 6. The array elements are 5 6 1 2 3 4. We use the arrayRotateCheck function to find the rotation index. Iteration 1: 5 > 6 (not true) Iteration 2: 6 > 1 (true) The current index (i) is 1, and i + 1 is 2. So, the rotation index is 2. The function returns 2. The output for the test case is 2.


public class Solution {

    public static int arrayRotateCheck(int[] arr){

        for(int i = 0 ; i < arr.length-1;i++){
            if(arr[i] > arr[i+1]){
                return i+1;
            }
     
        }
               return 0;
//      The input specifies there is 1 test case.

// For the first test case, the size of the array is 6.

// The array elements are 5 6 1 2 3 4.

// We use the arrayRotateCheck function to find the rotation index.

// Iteration 1: 5 > 6 (not true)
// Iteration 2: 6 > 1 (true)
// The current index (i) is 1, and i + 1 is 2.
// So, the rotation index is 2.
// The function returns 2.
// The output for the test case is 2.

Block vs Inline Elements In HTML

  Block: Block element always start in New Line  Block element always start in new line occupy complete width available  Example: h2, p, div Inline Element: They do not start in new line occuply width as much required  Example: img, anchor a,span There are no different between div and span, only difference is div is block element and span is Inline, it will help you to group your content or elements

Find Unique Number in Array Java , XOR

 Question:  WAP to find unique number in Array Java package aRray ; import java . util .*; public class practicalArray { public static void main ( String [] args ) { Scanner scan = new Scanner ( System . in ) ; // Step 1: Input size of the array from the user int size = scan . nextInt () ; // Step 2: Create an integer array of the specified size int [] arr = new int [ size ] ; // Step 3: Initialize 'res' with the first element of the array int res = arr [ 0 ] ; // Step 4: Loop to read array elements and find the unique number for ( int i = 1 ; i < size ; i ++ ) { // Read an integer from the user and store it in the array arr [ i ] = scan . nextInt () ; // Step 5: Use XOR (^) operation to find the unique number res = res ^ arr [ i ] ; } // Step 6: Print the unique number System . out . print...
