Zero One Knapsack | Recursion

1. You are given a number n, representing the count of items. 2. You are given n numbers, representing the values of n items. 3. You are given n numbers, representing the weights of n items. 3. You are given a number "cap", which is the capacity of a bag you've. 4. You are required to calculate and print the maximum value that can be created in the bag without overflowing it's capacity. Note: Each item can be taken 0 or 1 number of times. You are not allowed to put the same item again and again. Input Format A number n v1 v2 .. n number of elements w1 w2 .. n number of elements A number cap Output Format A number representing the maximum value that can be created in the bag without overflowing it's capacity Constraints 1 <= n <= 20 0 <= v1, v2, .. n elements <= 50 0 < w1, w2, .. n elements <= 10 0 < cap <= 10 Sample Input 5 15 14 10 45 30 2 5 1 3 4 7 Sample Output 75 Solution: import java.io.*; import java.util.*; public class Main...

Count Encodings

1. You are given a string str of digits. (will never start with a 0) 2. You are required to encode the str as per following rules 1 -> a 2 -> b 3 -> c .. 25 -> y 26 -> z 3. You are required to calculate and print the count of encodings for the string str. For 123 -> there are 3 encodings. abc, aw, lc For 993 -> there is 1 encoding. iic For 013 -> This is an invalid input. A string starting with 0 will not be passed. For 103 -> there is 1 encoding. jc For 303 -> there are 0 encodings. But such a string maybe passed. In this case print 0. Input Format A string str Output Format count of encodings Constraints 0 < str.length <= 10 Sample Input 123 Sample Output 3 Solution: import java.io.*; import java.util.*; public class Main { ...

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); ...
