Given a positive number N as input. The goal is to find the number of ways in which we can express N as a sum of 1s, 3s and 4s only. For example, if N is 4 then it can be represented as 1+1+1+1, 3+1, 1+3, 4 so the number of ways will be 4.Let us understand with examples.For ExampleInput - N=5Output - Count of different ways to express N as the sum of 1, 3 and 4 are: 6Explanation - 5 can be represented as:1+1+1+1+11+3+13+1+11+1+34+11+4Input - N=6Output - Count of different ways to express N as the sum of ...
