Target Sum Subsets - Dp

1. You are given a number n, representing the count of elements. 2. You are given n numbers. 3. You are given a number "tar". 4. You are required to calculate and print true or false, if there is a subset the elements of which add up to "tar" or not. Input Format A number n n1 n2 .. n number of elements A number tar Output Format true or false as required Constraints 1 <= n <= 30 0 <= n1, n2, .. n elements <= 20 0 <= tar <= 50 Sample Input 5 4 2 7 1 3 10 Sample Output true Solution: import java.io.*; import java.util.*; public class Main { public static void main(String[] args) throws Exception { Scanner sc = new Scanner(System.in); int n = sc.nextInt(); int[] arr = new int[n]; for(int i=0;i<n;i++) arr[i] = sc.nextInt(); int tar = sc.nextInt(); ...

Climb Stairs With Variable Jumps

1. You are given a number n, representing the number of stairs in a staircase. 2. You are on the 0th step and are required to climb to the top. 3. You are given n numbers, where ith element's value represents - till how far from the step you could jump to in a single move. You can of course jump fewer number of steps in the move. 4. You are required to print the number of different paths via which you can climb to the top. Input Format A number n .. n more elements Output Format A number representing the number of ways to climb the stairs from 0 to top. Constraints 0 <= n <= 20 0 <= n1, n2, .. <= 20 Sample Input 10 3 3 0 2 1 2 4 2 0 0 Sample Output 5 Solution: import java.io.*; import java.util.*; public class Main { public static void main(String[] args) throws Exception { // write your code here Scanner sc = new Scanner(System.in); ...

Count Binary Strings

1. You are given a number n. 2. You are required to print the number of binary strings of length n with no consecutive 0's. Note: In this problem, you are given a number n. All we need to print is the number of binary strings of length n with no consecutive 0's For example: Sample Input: 3 Sample Output: 5 How 5? We have a total of eight binary numbers for length 3, out of which we have 5 numbers in which there are no consecutive zeros. Input Format A number n Output Format A number representing the number of binary strings of length n with no consecutive 0's. Constraints 0 < n <= 45 Sample Input 6 Sample Output 21 Solution: import java.io.*; import java.util.*; public class Main{ public static void main(String[] args) throws Exception { // write your code here Scanner sc = new Scanner(System.in); int n = sc.nextInt(); int dp[][] = new int[n+1][2]; dp[1][0] = 1; dp[1][1] ...
