Heapsort 1.A heap is a binary tree satisfying the followingconditions: -This tree is completely ba

Heapsort 1.A heap is a binary tree satisfying the followingconditions: -This tree is completely balanced. -If the height of this binary tree is h, then leaves can be at level h or level h-1. -All leaves at level h are as far to the left as possible. -The data associated with all descendants of a node are smaller than the datum associated with this node. Implementation 1.using a linear array not a binary tree. -The sons of A(h) are A(2h) and A(2h+1). 2.time complexity: O(n log n)

最長(zhǎng)上升子序列非常經(jīng)典的問(wèn)題。給定的整數(shù)序列

最長(zhǎng)上升子序列非常經(jīng)典的問(wèn)題。給定的整數(shù)序列，請(qǐng)求出其最長(zhǎng)上升子序列的長(zhǎng)度。有多個(gè)測(cè)試用例。每個(gè)測(cè)試用例由一個(gè)行整數(shù)組成，其中第一個(gè)是一個(gè)整數(shù) n (1 ≤ n ≤ 10000)，表示給定序列的長(zhǎng)度。然后是 n 個(gè) 32-bits 帶符號(hào)整數(shù)表示序列中的元素。輸入直至沒(méi)有數(shù)據(jù)或者遇到長(zhǎng)度 n 是非正數(shù)為止。

FFT

FFT，即為快速傅氏變換，是離散傅氏變換的快速算法，它是根據(jù)離散傅氏變換的奇、偶、虛、實(shí)等特性，對(duì)離散傅立葉變換的算法進(jìn)行改進(jìn)獲得的。它對(duì)傅氏變換的理論并沒(méi)有新的發(fā)現(xiàn)，但是對(duì)于在計(jì)算機(jī)系統(tǒng)或者說(shuō)數(shù)字系統(tǒng)中應(yīng)用離散傅立葉變換，可以說(shuō)是進(jìn)了一大步。設(shè)x(n)為N項(xiàng)的復(fù)數(shù)序列，由DFT變換，任一X（m）的計(jì)算都需要N次復(fù)數(shù)乘法和N-1次復(fù)數(shù)加法，而一次復(fù)數(shù)乘法等于四次實(shí)數(shù)乘法和兩次實(shí)數(shù)加法，

fft analysis

Use the fast Fourier transform function fft to analyse following signal. Plot the original signal, and the magnitude of its spectrum linearly and logarithmically. Apply Hamming window to reduce the leakage. . The hamming window can be coded in Matlab as for n=1:N hamming(n)=0.54+0.46*cos((2*n-N+1)*pi/N); end; where N is the data length in the FFT.
