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"]...…
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 >=…
Count the number of segments in a string, where a segment is defined to be a contiguous sequence of non-space characters. Please note that the string does not contain any non-printable characters. Example: Input: "Hello, my name is John" Output:…
