1. Define the Input and Output.
2. Define entries in table, i.e. T(i) or T(i, j) is...
3. Define a Recurrence relationship - Based on a
Steps to solve a Dynamic subproblem to the main problem. (hint: use a prefix of
Programming Problem the original input 1 < i < n).
4. Define the Pseudocode.
5. Define the Runtime of the algorithm. Use Time
Function notation here => T(n) = T(n/2) + 1...
Input = x1, x2, ..., xn
1) Subproblem = x1, x2, ..., xi ; O(n)
2) Subproblem = xi, xi+1, ..., xj ; O(n^2)
DP: Types of Subproblems Input = x1, x2, ..., xn; y1, y2, ..., ym
(4) 1) Subproblem = x1, x2, ..., xi; y1, y2, ..., yj ; O(mn)
Input = Rooted Binary Tree
1) Subproblem = Smaller rooted binary tree inside the
Input.
Given r = common ratio and a = first term in series
=> a + ar + ar^2 + ar^3 + ... + ar^(n-1)
DC: Geometric Series
=> a * [(1 - r^n) / (1-r)]
Given d = common difference and a = first term in
series => a + (a + d) + (a + 2d) + ... + (a + (n-1)d
DC: Arithmetic Series
Sum = n/2 [2a + (n-1)d]
