How do you find the common elements in two sorted arrays?

To find union of two sorted arrays, follow the following merge procedure :

1. Use two index variables i and j, initial values i = 0, j = 0.
2. If arr1[i] is smaller than arr2[j] then print arr1[i] and increment i.
3. If arr1[i] is greater than arr2[j] then print arr2[j] and increment j.

How do you find all pairs of elements in an array whose sum is equal to a given number?

How to find all pairs of elements in Java array whose sum is equal to a given number?

1. Add each element in the array to all the remaining elements (except itself).
2. Verify if the sum is equal to the required number.
3. If true, print their indices.

How do you find all pairs of an integer array whose sum is equal to a given number in Javascript?

function arraypair(array,sum){ for (i = 0;i < array. length;i++) { var first = array[i]; for (j = i + 1;j < array. length;j++) { var second = array[j]; if ((first + second) == sum) { alert(‘First: ‘ + first + ‘ Second ‘ + second + ‘ SUM ‘ + sum); console.

How do you find the common elements in three sorted arrays?

Let the current element traversed in ar1[] be x, in ar2[] be y and in ar3[] be z. We can have following cases inside the loop. If x, y and z are same, we can simply print any of them as common element and move ahead in all three arrays. Else If x < y, we can move ahead in ar1[] as x cannot be a common element.

How do you find the length of an array in C?

Calculate the size of the array using sizeof operator e.g. sizeof(arr). Calculate the size of an int value using sizeof(int). To get the length of the array( number of elements), divide total size of array by size of 1 int.

How do you check if two arrays are equal?

Solution Steps

1. Compare the lengths of arr1 and arr2 .
2. Sort arr1 and arr2 either in ascending or descending order.
3. For each index i of the array, compare arr1[i] and arr2[i] to be equal.
4. If at any point the condition fails, then return False otherwise, at the end of the comparison, return True .

How do you find a pair?

Given an array A of N numbers, find the number of distinct pairs (i, j) such that j >=i and A[i] = A[j]. First line of the input contains number of test cases T. Each test case has two lines, first line is the number N, followed by a line consisting of N integers which are the elements of array A.

How do you find the nearest Pair in a sorted array?

Given a sorted array and a number x, find a pair in array whose sum is closest to x. A simple solution is to consider every pair and keep track of closest pair (absolute difference between pair sum and x is minimum). Finally, print the closest pair.

How do you find the sum of a sorted array?

Given a sorted array and a number x, find a pair in array whose sum is closest to x. Examples: A simple solution is to consider every pair and keep track of closest pair (absolute difference between pair sum and x is minimum). Finally print the closest pair. An efficient solution can find the pair in O(n) time.

How to find the minimum diff of a sorted array?

The following is a detailed algorithm. 1) Initialize a variable diff as infinite (Diff is used to store the difference between pair and x). We need to find the minimum diff. 2) Initialize two index variables l and r in the given sorted array.

How to find the smallest difference between two arrays of integers?

Smallest Difference pair of values between two unsorted Arrays. Given two arrays of integers, compute the pair of values (one value in each array) with the smallest (non-negative) difference. Return the difference. Examples : A simple solution is to Brute Force using two loops with Time Complexity O(n 2). A better solution is to sort the arrays.
