等号左侧、右侧分别相加,得到a1+a2+a3=b1-b2+b2-b3+b3-b1=0 如果是 a1=b1-b2 a2=b2-b3 a3=b1-b3 可以得到a1+a2-a3=0 继续推可以发现,若给ai带上正负号求和,那么这个环一定有一种方式求和为0 所以我们就可以枚举ai的符号(0,-1,1)求和 #include<bits/stdc++.h>usingnamespacestd;inta[11];intma...
26. 这个想法挺妙的,但似乎也没有什么具体的算法在,在训练上也只能通过不断做这样的思维题来达到了。
CF1552 D. Array Differentiation Problem - 1552D - Codeforces 题意: 给出一个有n个数的数组a,能否构造出一个长为n的数组b,使a中的每个数都可以由b中某两个数相减得到。 令b[1]等于任意值,b[i]=a[i-1]+b[1],这样可以很容易的使a中的n-1个数满足要求 剩下一个数比较难搞 若...

Forgetting about dimension reduction: Remember, np.diff() returns an array with one less element along the differentiation axis. Always account for this in your code. Using incorrect axis: When working with multi-dimensional data, selecting the wrong axis for differentiation can lead to unexpected ...
