t(n)=2t(n/2)+n^3

解答

t (n) = 2 t (\frac{n}{2}) + n^{3}

对所有 t 为真; 0 = n^{3}

求解步骤

t (n) = 2 t (\frac{n}{2}) + n^{3}

去除括号:

(a) = a

t (n) = 2 t \frac{n}{2} + n^{3}

2 t \frac{n}{2} = n t

t (n) = n t + n^{3}

展开

t (n) : n t

n t = n t + n^{3}

将

n t

para o lado esquerdo

0 = n^{3}

两侧相等

对所有 t 为真; 0 = n^{3}

0.4 (1 + m) = 0.3 (1 - m)

so l v e f or x, - 3 x - y = - 6

\frac{c + 12}{5} = \frac{21}{10}

c = (11111111) 2

11.4 = \frac{( 89 + 2 x )}{10}
