牛客网contest#91 A Wasserstein Distance 贪心
题解: 1、线性扫描数组,两个数组相同下标元素不相等的就开始到数组后面去找数据来补。 2、例如a[0]<b[0],那么就从下标1开始,向后寻找a[i]>b[i]的数据来补齐,注意考虑寻找到的数据差值比较就行了 3、注意输出数据会爆int。 #include <bits/stdc++...
UVA 11796 - Dog Distance
题意 两条狗啊,同时跑,,同时结束,各自跑各自的道路,问跑的过程中,他们最大距离和最小距离的差;方法 恶心一点就是,最大最小距离的求解方法,假设两只狗都只有一条线段要跑,则可以判定在端点处有最大值,最小值的求解方法就是,把一条狗的奔跑方向分解成另一个狗的奔跑方向 + 另外一个向量,这样这条狗相对...
