c++符号三角算法:
符号三角形问题要求对于给定的n,计算有多少个不同的符号三角形,使其所含的 + 和 - 的个数相同。
在一般情况下,符号三角形的第一行有n个符号。如图所示是由14个 + 号和14个 - 号组成的符号三角形。两个同号下面都是 + ,两个异号下面都是 - 号。-Symbol Triangles requirements for a given n, calculate how many different symbols triangle, the + and contained- the same number of .
In general, the first line of the triangle symbol has n symbols. As shown in Figure 14 is a + sign and 14- symbol triangle number consisting of . Here are the number two with + , two different numbers below are - sign.
