[C++ code] Merge intervals, use the minimum number of arrows, divide strings, monitor binary trees, greedy algorithms – Code Thoughts

In the explanation [Greedy Algorithm: Rebuilding the Queue Based on Height, we mentioned that using vector (dynamic array in C++) to perform insert operations is time-consuming. Intuitively, the insert operation of the array is O(n), and the time complexity of the overall code is O(n^2). For ordinary arrays, once the size is defined, it cannot […]

[C++ Code] Divide sugar, divide biscuits, swing sequence, greedy algorithm–Code Random Record

The essence of greed is to select the local optimum at each stage to achieve the global optimum. Simulate manually by yourself. If the simulation is feasible, you can try the greedy strategy. If it is not feasible, you may need dynamic programming. The greedy algorithm is generally divided into the following four steps: Break […]
