Dynamic Programming Questions
The Maximum Sum of Subsequence with No Fifty-Three Consecutive Elements problem is a dynamic programming problem that involves finding the maximum sum of a subsequence from a given sequence, with the constraint that no two consecutive elements in the subsequence can be 53.
To solve this problem using dynamic programming, we can use an array to store the maximum sum of subsequences ending at each index. Let's call this array dp.
We initialize dp[0] as the first element of the sequence, and dp[1] as the maximum of the first two elements. For all other indices i, we calculate dp[i] as the maximum of the following two options:
1. If the element at index i is 53, then dp[i] = dp[i-2] + sequence[i]. This is because we cannot include the element at index i in the subsequence, so we skip it and take the maximum sum of the subsequence ending at index i-2 and add the current element.
2. If the element at index i is not 53, then dp[i] = max(dp[i-1], dp[i-2] + sequence[i]). This is because we have the option to either include the current element in the subsequence or skip it. If we include it, we take the maximum sum of the subsequence ending at index i-2 and add the current element. If we skip it, we take the maximum sum of the subsequence ending at index i-1.
Finally, the maximum sum of the subsequence with no fifty-three consecutive elements will be the maximum value in the dp array.
By using this dynamic programming approach, we can efficiently solve the Maximum Sum of Subsequence with No Fifty-Three Consecutive Elements problem.
