Dahasolnce [82]3 years ago
6 0

Answer:

Explanation:

A disk block works by transferring data between the disk and main memory units which are called the blocks, whose size can range drastically from 512 bytes to several thousand.  This data is converted to hardware-level cylinder, surface, and sector number  which makes accessing the data immensely slower than accessing data in the main memory. This time constraint is also the main reason as to why accessing a disk block is so expensive.

Write a java program to read elements in an array from user and count total number of duplicate elements in array.
Anna11 [10]

Answer:

Explanation:

The following code is written in Java and is a function/method that takes in an int array as a parameter. The type of array can be changed. The function then creates a counter and loops through each element in the array comparing each one, whenever one element is found to be a duplicate it increases the counter by 1 and moves on to the next element in the array. Finally, it prints out the number of duplicates.

public static int countDuplicate (int[] arr) {

               int count = 0;

               for(int i = 0; i < arr.length; i++) {

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

                               if(arr[i] == arr[j])

                                       count++;

                       }

               }

               return count;

       }
