Given an infinite number of quarters (25 cents), dimes (10 cents), nickels (5 cents) and pennies (1 cent), find how many ways to represent n cents. 思路: 从最大面值的硬币开始分析,然后依次看更小面值的硬币.假设 n = 100, 所有 valid 排列组合中 num_quarters = 0 的是一类, num_quarters = 1 的是一类,

今天开始学习head first javascript,之前在慕课网和网易云课堂上都学习了javascript,但还是丈二和尚摸不着头脑,于是觉得可能是自己的基础较薄,因此选择这本简单有趣的入门读物,希望能带我入门,加油! 第一章 1.JavaScript把网页转变成了交互式应用程序: 2.<script>标签向浏览器表示以下为JavaScript,<script type="text/javascript"></script>一般放在<hea

18.9 Numbers are randomly generated and passed to a method. Write a program to find and maintain the median value as new values are generated. LeetCode上的原题,请参见我之前的博客Find Median from Data Stream. 解法一: priority_queue<int> small; priority_queue<int,

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

Write a function for retrieving the total number of substring palindromes. For example the input is 'abba' then the possible palindromes= a, b, b, a, bb, abba So the result is 6. Updated at 11/11/2013: After the interview I got know that the O(n^3) s
