To find common elements in two sorted arrays using JavaScript, we will be discussing various approaches. Common element refers to element which is present in both the arrays. First, we will try brute force approach and then we will optimize our code to improve the time complexity....
for (int i = 0; i < array1.length; i++) { for (int j = 0; j < array2.length; j++) { // Check if elements in array1 and array2 are equal. if (array1[i].equals(array2[j])) { // Add the common element to the HashSet. set.add(array1[i]); } } } // Print th...
("Array1 : "+Arrays.toString(array1));System.out.println("Array2 : "+Arrays.toString(array2));for(inti=0;i<array1.length;i++){for(intj=0;j<array2.length;j++){if(array1[i]==(array2[j])){// return common integer value.System.out.println("Common element is : "+(array1[i...

As you might already know, PostgreSQL supports arrays. This special data type allows you to store multiple values in a single column as an array. When working with arrays, one of the most common operations is searching for elements within them. Let's explore PostgreSQL find in array ...
