两种方式处理已经访问过的节点:一种是用visited存储已经访问过的1:另一种是通过改变原始数值的值,比如将1改成-1,这样小于等于0的都会停止. Number of Islands 用了第一种方式,Number of Distinct Islands用了第二种方式 200. Number of Islands 时间复杂度o(m*n) 1.这种写法要改变原始输入数组的值 错误版本: 条件判断顺序写错:grid[x][y] == '0' || x < 0 || x >= length || y…

18.4 Write a method to count the number of 2s between 0 and n. 这道题给了我们一个整数n,让我们求[0,n]区间内所有2出现的个数,比如如果n=20,那么满足题意的是2, 12, 20,那么返回3即可.LeetCode上有一道很类似的题Factorial Trailing Zeroes,但是那道题求5的个数还包括了因子中的5,比如10里面也有5,这是两题的不同之处.那么首先这题可以用brute force来解,我们对区间内的每一个数字…

Description: Count the number of prime numbers less than a non-negative number, n. 思路:这题第一种思路是写一个is_prime函数,来对每一个数验证一次是否是prime. 这个方法在这个题里表现不快,但也是一个学习is_prime函数的机会. 首先,验证一个数是不是prime,只需要用小于它的所有正整数全除一遍看是否能整除就行.实际上,我们只需要试验到sqrt(n),不需要到n-1.因为假如p * q = n的话…
