问题描述

我试图解决这个复发

T(N)= 3 T(N / 2)+ N LG电子ñ。

T(n) = 3 T(n/2) + n lg n ..

我是来它是属于主人定理2的情况下由于n LG电子n中的解决方案是O(n ^ 2)

I have come to the solution that it belongs to masters theorem case 2 since n lg n is O(n^2)

但指的是解决方案手册后,我注意到了这个解决方案,他们有

but after referring to the solution manual i noticed this solution that they have

该soluttion说是n LG N =为O(n ^(LG 3 - E))为0和0.58Ë

The soluttion says that n lg n = O ( n ^(lg 3 - e)) for e between 0 and 0.58

所以这表示正LG n是O(n)的..这是正确的?我失去了一些东西呢?

so this means n lg n is O(n) .. is this right? Am i missing something here?

是不是nlgn为O(n ^ 2)?

Isn't nlgn O(n^2) ?
