Episode Synopsis "Coin Change Permutations"

1. You are given a number n, representing the count of coins. 2. You are given n numbers, representing the denominations of n coins. 3. You are given a number "amt". 4. You are required to calculate and print the number of permutations of the n coins using which the     amount "amt" can be paid. Note1 -> You have an infinite supply of each coin denomination i.e. same coin denomination can be                  used for many installments in payment of "amt" Note2 -> You are required to find the count of permutations and not combinations i.e.                  2 + 2 + 3 = 7 and 2 + 3 + 2 = 7 and 3 + 2 + 2 = 7 are different permutations of same                  combination. You should treat them as 3 and not 1. Input Format A number n n1 n2 .. n number of elements A number amt Output Format A number representing the count of combinations of coins which can be used to pay the amount "amt" Constraints 1 <= n <= 20 0 <= n1, n2, .. n elements <= 20 0 <= amt <= 30 Sample Input 4 2 3 5 6 7 Sample Output 5 --- Send in a voice message: https://podcasters.spotify.com/pod/show/rahulsain/message
