1053 Path of Equal Weight (30 分) Given a non-empty tree with root R, and with weight Wi assigned to each tree node Ti. The weight of a path from R to L is defined to be the sum of the weights of all the nodes along the path from R to any leaf…
The K−P factorization of a positive integer N is to write N as the sum of the P-th power of K positive integers. You are supposed to write a program to find the K−P factorization of N for any positive integers N, K and P. Input Specification: Each in…
One way that the police finds the head of a gang is to check people's phone calls. If there is a phone call between A and B, we say that A and B is related. The weight of a relation is defined to be the total time length of all the phone calls made b…
题意:大致就是要求画出这个有规律的Fractal图形了= = 例如 1 对应 X 2 对应 X X X X X 这个题是个理解分治法很典型的例子(详情请参见Code) 分治法:不断缩小规模,以致把整个大问题分解为若干个可以直接处理的小问题,一般通过递归调用实现,可以用极简代码完成高复杂的工作,但空间与时间占用也相对较大. //分治法画图 //Memory:880K Time:16 Ms #include<iostream> #include<cstring> #inc…
