The transpose of a matrix is the one whose rows are columns of the original matrix, i.e. if A and B are two matrices such that the rows of the matrix B are the columns of the matrix A then Matrix B is said to be the transpose of Matrix A.To print the transpose of the given matrix −Create an empty matrix.Copy the contents of the original matrix to the new matrix such that elements in the [j][i] position of the original matrix should be copied to the [i][j] position of the new matrix.Print the new matrix.ExampleLive Demopublic class TransposeSample{ ...

In the loop check, the result of I %2 operation on each element, if 0 the element is even else the element is odd.ExampleLive Demopublic class OddNumbersInAnArray {    public static void main(String args[]){       int[] myArray = {23, 93, 56, 92, 39};       System.out.println("Even numbers in the given array are:: ");       for (int i=0; i

To add two matrices −Create an empty matrixAt each position in the new matrix, assign the sum of the values in the same position from the given two matrices i.e. if A[i][j] and B[i][j] are the two given matrices then, the value of c[i][j] should be A[i][j] + B[i][j]ExampleLive Demopublic class AddingTwoMatrices{    public static void main(String args[]){       int a[][]={{1,2,3},{4,5,6},{7,8,9}};       int b[][]={{1,1,1},{1,1,1},{1,1,1}};       int c[][]=new int[3][3];       for(int i = 0;i

To find the smallest element of the given array, first of all, sort the array.Sorting an arrayCompare the first two elements of the arrayIf the first element is greater than the second swap them.Then, compare 2nd and 3rd elements if the second element is greater than the 3rd swap them.Repeat this till the end of the array.After sorting an array print the 1st element of the array.ExampleLive Demopublic class SmallestNumberInAnArray {    public static void main(String args[]){       int temp, size;       int array[] = {10, 20, 25, 63, 96, 57};       size = array.length;       for(int i = 0; i

To find the 2nd smallest element of the given array, first of all, sort the array.Sorting an arrayCompare the first two elements of the arrayIf the first element is greater than the second swap them.Then, compare 2nd and 3rd elements if the second element is greater than the 3rd swap them.Repeat this till the end of the array.After sorting an array print the 2nd element of the array.ExampleLive Demopublic class SmallestNumberInAnArray {    public static void main(String args[]){       int temp, size;       int array[] = {10, 20, 25, 63, 96, 57};       size = array.length;       for(int i = 0; i

To find the largest element of the given array, first of all, sort the array.Sorting an arrayCompare the first two elements of the arrayIf the first element is greater than the second swap them.Then, compare 2nd and 3rd elements if the second element is greater than the 3rd swap them.Repeat this till the end of the array.After sorting an array print the 1st element from the end of the array.ExampleLive Demopublic class ThirdLargestNumberInAnArray {    public static void main(String args[]){       int temp, size;       int array[] = {10, 20, 25, 63, 96, 57};       size = array.length;       for(int i = 0; i

To find the second largest element of the given array, first of all, sort the array.Sorting an arrayCompare the first two elements of the arrayIf the first element is greater than the second swap them.Then, compare 2nd and 3rd elements if the second element is greater than the 3rd swap them.Repeat this till the end of the array.After sorting an array print the second element from the end of the array.ExampleLive Demopublic class ThirdLargestNumberInAnArray {    public static void main(String args[]){       int temp, size;       int array[] = {10, 20, 25, 63, 96, 57};       size = array.length;       for(int i = 0; i

To find the third largest number of the given array, first of all, sort the array.Sorting an arrayCompare the first two elements of the arrayIf the first element is greater than the second swap them.Then, compare 2nd and 3rd elements if the second element is greater than the 3rd swap them.Repeat this till the end of the array.After sorting an array print the third element from the end of the array.ExampleLive Demopublic class ThirdLargestNumberInAnArray {    public static void main(String args[]){    int temp, size;    int array[] = {10, 20, 25, 63, 96, 57};    size = array.length;        for(int i = 0; i

Linear search is a very simple search algorithm. In this type of search, a sequential search is done for all items one by one. Every item is checked and if a match is found then that particular item is returned, otherwise the search continues till the end of the data collection.Algorithm1.Get the length of the array. 2.Get the element to be searched store it in a variable named value. 3.Compare each element of the array with the variable value. 4.In case of a match print a message saying element found. 5.else, print a message saying element not foundExampleLive Demopublic class ...

Binary search is a fast search algorithm with run-time complexity of Ο(log n). This search algorithm works on the principle of divide and conquer. For this algorithm to work properly, the data collection should be in the sorted form.The binary search looks for a particular item by comparing the middle most item of the collection. If a match occurs, then the index of the item is returned. If the middle item is greater than the item, then the item is searched in the sub-array to the left of the middle item. Otherwise, the item is searched for in the sub-array to the right ... Read More
