Coin Change Combination

By Astrio Jather
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. Note 1: You have an infinite supply of each coin denomination i.e. same coin denomination can be                    used for many installments in payment of "amt" Note 2: 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. Input Format A number n n1 n2 .. n number of elements A number amt Output Format A number representing the count of ...

Goldmine

By Astrio Jather
1. You are given a number n, representing the number of rows. 2. You are given a number m, representing the number of columns. 3. You are given n*m numbers, representing elements of 2d array a, which represents a gold mine. 4. You are standing in front of left wall and are supposed to dig to the right wall. You can start from       any row in the left wall. 5. You are allowed to move 1 cell right-up (d1), 1 cell right (d2) or 1 cell right-down(d3). 6. Each cell has a value that is the amount of gold available in the cell. 7. You are required to identify the maximum amount of gold that can be dug out from the mine. Input Format A number n A number m e11 e12.. e21 e22.. .. n * m number of elements Output Format An integer representing Maximum gold available. Constraints 1 <= n <= 10^2 1 <= m <= 10^2 0 <= e1, e2, .. n * m elements <= 1000 Sample Input 6 6 0 1 4 2 8 2 4 3 6 5 0 4 1 2 4 1 4 6 2 0 7 3 2 2 3 1 5 9 2 4 2 7 0 8 5 1 Sample Output 33 Solution:...
