   How to find the sum of elements in a 2D array?

   • We can also use pointers to find the sum of elements in a 2D array. We can use a pointer to point to the first element of the array and iterate through each element in the array by incrementing the pointer. Step by Step algorithm : Define a function named sum that takes a 2D array of integers as input and returns an integer value.

   How do you sum a 2D array using a loop?

   • Declare an integer variable sum and initialize it to zero. Using a loop that iterates over the elements of the 2D array, add each element to sum by dereferencing the pointer p. Return the sum value. Time Complexity: O (M*N) This is because the function sum () iterates through each element of the matrix using a pointer, taking O (M*N) time.

   The simplest way to find the sum of two arrays is by iterating over each corresponding element and adding them together. Let's assume we have two arrays, array1 and array2, of the same length n. Here's an example implementation using a for loop: File Name: SumOfTwoArrays.java. public class SumOfTwoArrays { public static void main (String [] args) {
