In this video, we discuss the solution for the coin change combination problem where we need to find the combinations of numbers which sum up to a certain target where each number can be used repetitively. In this problem, 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 combinations 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 combinations and not permutations 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 1 and not 3.
