Maximum sum possible for a sub | Function to return the maximum sum possible.
dp [ i ] represent the maximum sum so far after reaching current position i.
Initialize dp [ 0 ].
Initialize the dp values till k since any two elements included in the sub - sequence must be atleast k indices apart , and thus first element and second element will be k indices apart.
Fill remaining positions.
Return the maximum sum.
Driver code"
How can the above be solved in Python?

Give me a code to maximum sum possible for a sub and the other steps required?
