LeetCode-Find All Numbers Disappeared in an Array Description: Given an array of integers where 1 ≤ a[i] ≤ n (n = size of array), some elements appear twice and others appear once. Find all the elements of [1, n] inclusive that do not appear in this array. Could you do it wit...
Sometimes we need to find numeric digits or full numbers in strings. We can do this with both regular expressions or certain library functions. In this article, we’lluse regular expressions to find and extract numbers in strings. We’ll also cover some ways to count digits. 2. Counting Nu...

Take maximum of the two numbers and continue producing the multiples of this number until it is also the multiple of smaller number. Or there is another tedious method of finding prime factors of both numbers and union them. product of all union numbers gives you LCM. ...
Below is an example of a Java program to find the sum of N numbers using recursion import java.util.Scanner; public class ArraySum { public static int RecursiveSum(int my_array[], int i,int N){ if (i == N) return 0; return my_array[i] + RecursiveSum(my_array, i + 1,N); ...
