以下是这一道题打表时间复杂度较低而且容易上手的方法，适合初学者学习！ ~~**其实就是打表**~~ ```cpp #include using namespace std; int main(){ unsigned int powers[32]={1,2,4,8,16,32,64,128,256,512,1024,20…

**先贴出代码** ```python import pulp from math import * angle=float(input("θi=")) angle=pi*(angle/360) altitude=float(input("θ=")) altitude=pi*(altitude/360) i=float…
