Necklace Merging Optimization Using Interval Dynamic Programming
Circular Array Trensformation
To handle circular arrangements, duplicate the necklace elements:
for (int idx = 0; idx < n; idx++)
elements[idx + n] = elements[idx];
Dynamic Programming Formluation
Define energyMatrix[i][j] as the maximum energy obtianed by merging the interval from index i to j. The state transition equation is:
\[ \te ...

Matchstick Equation Generation Algorithm
Matchstick Equation Problem
Problem Description
Given n matchsticks, determine how many equations of the form "A+B=C" can be formed. A, B, and C are integers constructed using matchsticks (if non-zero, the highest digit cannot be 0). The matchstick requirements for digits 0-9 are provided in a reference diagram.
Constraints:
The plus ...
