Maximum subsequence sum with adjacent elements having atleast K difference in index | Function to find the maximum sum subsequence such that two adjacent element have atleast difference of K in their indices.
DP Array to store the maximum sum obtained till now.
Either select the first element or Nothing.
Either Select the ( i - 1 ) element or let the previous best answer be the current best answer.
Either select the best sum till previous_index or select the current element + best_sum till index - k.
