参加腾讯前端实习生笔试,真的是被虐了千百遍,除了一条js程序题,其他半点前端都没有,都是考算法,计算机原理,数据结构.下面贴上腾讯笔试最后三大条中的一条,实现一个蛇形矩阵的输出.蛇形矩阵的什么样这里我就不多说了. var lineCount=0; var numCount=1; var lineLog=1; var doubleArray=[]; var result="result:"; var lineCountGet; function index (n) { ArrayMake…
Given a n x n matrix where each of the rows and columns are sorted in ascending order, find the kth smallest element in the matrix. Note that it is the kth smallest element in the sorted order, not the kth distinct element. Example: matrix = [ [ 1, 5…
Given an integer matrix, find the length of the longest increasing path. From each cell, you can either move to four directions: left, right, up or down. You may NOT move diagonally or move outside of the boundary (i.e. wrap-around is not allowed). E…
An image is represented by a binary matrix with 0 as a white pixel and 1 as a black pixel. The black pixels are connected, i.e., there is only one black region. Pixels are connected horizontally and vertically. Given the location (x, y) of one of the…
Write an efficient algorithm that searches for a value in an m x n matrix. This matrix has the following properties: Integers in each row are sorted in ascending from left to right. Integers in each column are sorted in ascending from top to bottom.…
Write an efficient algorithm that searches for a value in an m x n matrix. This matrix has the following properties: Integers in each row are sorted from left to right. The first integer of each row is greater than the last integer of the previous ro…
Given a m x n matrix, if an element is 0, set its entire row and column to 0. Do it in place. click to show follow up. Follow up: Did you use extra space?A straight forward solution using O(mn) space is probably a bad idea.A simple improvement uses O…
Given a matrix of m x n elements (m rows, n columns), return all elements of the matrix in spiral order. For example,Given the following matrix: [ [ 1, 2, 3 ], [ 4, 5, 6 ], [ 7, 8, 9 ] ] You should return [1,2,3,6,9,8,7,4,5]. 这道题让我们将一个矩阵按照螺旋顺序打印出来,我们…
在python中,实现多维数组或矩阵,有两种常用方法: 内置列表方法和numpy 科学计算包方法. 下面以创建10*10矩阵或多维数组为例,并初始化为0,程序如下: # Method 1: list arr1 = [[0]*10 for i in range(10)] arr1[0][0] = 1 print "Method 1:\n", arr1 arr2 = [[0 for i in range(10)] for i in range(10)] arr2[0][0] = 1 pri…
题目链接 题意: 思路: 直接拿别人的图,自己写太麻烦了~ 然后就可以用矩阵快速幂套模板求递推式啦~ 另外: 这题想不到或者不会矩阵快速幂,根本没法做,还是2013年长沙邀请赛水题,也是2008年Google Codejam Round 1A的C题. #include <bits/stdc++.h> typedef long long ll; const int N = 5; int a, b, n, mod; /* *矩阵快速幂处理线性递推关系f(n)=a1f(n-1)+a2f(n-2)+.…
