三色球问题 若有一个口袋放有12个球,其中有3个红的,3个白的和6个黑的,从中任取8个球, 问共 这也是一个可用穷举法求解的问题。 设任取的红球个数为i, 白球个数为 j,则黑球个数为8-i-j,用count统计不同的搭配数目- Three chromospheres questions if have a pocket to put have 12
balls, including 3 red, 3 white and 6 black, no matter what takes 8
balls, asked altogether this also is may use the question which the
exhaustion method solves. Supposes no matter what takes the red ball
integer is i, the white ball integer is j, then the black ball integer
is 8-i-j, counts differently with count matches the number
刚才弄错了,这才是第二个源码,可以实现输入一二叉树的前序与中序,输出其后序-have just made a mistake, this is the second source, can achieve an input sequence of binary tree with the sequence, then the output sequence
DFP变尺度法,包括一维搜索法,黄金分割法,采用类封装,包括矩阵类,变尺度类。实现简单明了。-DFP variable metric method, including the one-dimensional search, golden section method, type of packaging used, including matrix-type, variable-scale category. Simple to achieve.
