Find all pairs of an integer array or list whose sum is equal to a given number

Ex:-   [ 2, 4, 3, 5, 1, 6, 0 ]     and  5

                 (2, 3)  ==> 2 + 3 = 5

                 (4, 1) ==> 4 + 1 = 5

                 (5, 0) ==> 5 + 0 = 5

 public class ArraySum  {
     public static void main(String []args){
        int[] arr = {2, 4, 3, 5, 1, 6, 0};
        int given_sum = 5;
        for(int i=0; i<arr.length; i++)
            for(int j=i+1; j<arr.length; j++)
                if(arr[i]+arr[j]==given_sum)
                    System.out.println(arr[i]+" "+arr[j]);
     }
 }

Python

given_list = [2, 4, 3, 5, 1, 6, 0]
given_sum = 5
for i in range(0,len(given_list)):
    if given_sum-given_list[i] in given_list[i+1:]:
        print(given_list[i], given_sum-given_list[i])

Check whether a number is Seed of another number

 A number P is said to be the seed of another number Q if multiplying P with its digits equates to Q. Ex:-  123 is seed of 738 as    123 * 1 * 2 * 3 = 738  Java 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 public class Seed{ public static void main (String[] args){ int num1 = 123 , num2 = 738 ; num1 = Math. min (num1,num2); num2 = Math. max (num1,num2); System. out . println (checkSeed(num1, num2)); } public static boolean checkSeed ( int num1, int num2){ int seed = num1; while (num1> 0 ){ seed = seed * (num1% 10 ); num1 = num1 / 10 ; } if (seed==num2) return true ; else return false ; } } Python def checkSeed(num1,num2): seed = num1 while num1 > 0 : seed = seed * (num1 % 10 ) num1 = num1 // 10 if seed == n

Program to sort the first half of an array in ascending and second half in descending order

Ex:-  [2, 4, 3, 10, 5, 8] [2, 4, 3]  and [10, 5, 8] ====>  [2, 3, 4] ascending                                                              [10, 8, 5] descending [ 2, 3, 4, 10, 8, 5] is the required answer.  Java 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 public class ArraySort{ public static void main (String[] args){ int [] arr = { 2 , 4 , 3 , 10 , 5 , 8 }; //sorting first half in ascending order for ( int i= 0 ; i<(arr. length / 2 ); i++){ for ( int j=i+ 1 ; j<(arr. length / 2 ); j++){ if (arr[i]>arr[j]){ int temp = arr[i]; arr[i] = arr[j]; arr[j] = temp; } } } //sorting second half in descending order for ( int i=(arr. length / 2 ); i<arr. length ; i++){ for ( int j=i+ 1 ; j<arr. length ; j++)
