标题:
关于2-HEIGHT
(53) Ds 2-HEIGHT被定义为:X的最大因子2^N 的N, K 和M都是政整数,
问K的2-HEIGHT是否大于M的2-HEIGHT
i). K>M
ii).K/M为一个偶数
偶选B
[确认]B
[思路]i) 反例:K=3, M=2 ,ii) K的2-HEIGHT至少比M的2-HEIGHT大一
问题:我还是没明白2-HEIGHT指什么?

for examples:
8=2^3 =>
2-HEIGHT of 8 is 3
9=2^0*3^2=> 9 has 2-height 0 ( maybe you can define 3- height by your self, it will be 2
)
100= 2^2*5^2
100 has 2- height 2
it is the positive power of the 2 in the factorization expression of that number.
