We are to write the letters of a given string S, from left to right into lines. Each line has maximum width 100 units, and if writing a letter would cause the width of the line to exceed 100 units, it is written on the next line. We are given an arra…
problem 806. Number of Lines To Write String solution: class Solution { public: vector<int> numberOfLines(vector<int>& widths, string S) { , len = ; for(auto ch:S) { int t = widths[ch-'a']; ) line++; len = (len+t>) ? t : len+t; } return…
Question 806. Number of Lines To Write String Solution 思路:注意一点,如果a长度为4,当前行已经用了98个单元,要另起一行. Java实现: public int[] numberOfLines(int[] widths, String S) { int left = 0; int lines = 0; for (char c : S.toCharArray()) { left += widths[c - 'a']; if (left >=…
806. Number of Lines To Write String 整体思路: 先得到一个res = {a : 80 , b : 10, c : 20.....的key-value对象}(目的是当调用res["a"]时得到一个等于10的值): 遍历传入的字符串,把每个元素带入到res中,并把所有的值进行累加:得到一个累加值sum,如:sum= sum + res["a"] + res["b"] + res["c"]...…

Given n points in the plane that are all pairwise distinct, a "boomerang" is a tuple of points (i, j, k) such that the distance between i and j equals the distance between i and k (the order of the tuple matters). Find the number of boomerangs.…
Given a positive integer, output its complement number. The complement strategy is to flip the bits of its binary representation. Note: The given integer is guaranteed to fit within the range of a 32-bit signed integer. You could assume no leading ze…
Given a string, find the first non-repeating character in it and return it's index. If it doesn't exist, return -1. Examples: s = "leetcode" return 0. s = "loveleetcode", return 2. Note: You may assume the string contain only lowercase…
