806.Number of Lines to Write String

806.Number of Lines to Write String
难度:Easy
我们要把给定的字符串 S 从左到右写到每一行上，每一行的最大宽度为100个单位，如果我们在写某个字母的时候会使这行超过了100 个单位，那么我们应该把这个字母写到下一行。我们给定了一个数组 widths ，这个数组 widths[0] 代表 'a' 需要的单位， widths[1] 代表 'b' 需要的单位，...， widths[25] 代表 'z' 需要的单位。
现在回答两个问题：至少多少行能放下S，以及最后一行使用的宽度是多少个单位？将你的答案作为长度为2的整数列表返回。
示例 1:
输入: 
widths = [10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10]
S = "abcdefghijklmnopqrstuvwxyz"
输出: [3, 60]
解释: 
所有的字符拥有相同的占用单位10。所以书写所有的26个字母，
我们需要2个整行和占用60个单位的一行。
示例 2:
输入: 
widths = [4,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10]
S = "bbbcccdddaaa"
输出: [2, 4]
解释: 
除去字母'a'所有的字符都是相同的单位10，并且字符串 "bbbcccdddaa" 将会覆盖 9 * 10 + 2 * 4 = 98 个单位.
最后一个字母 'a' 将会被写到第二行，因为第一行只剩下2个单位了。
所以，这个答案是2行，第二行有4个单位宽度。
 
​
注:
​
字符串 S 的长度在 [1, 1000] 的范围。
S 只包含小写字母。
widths 是长度为 26的数组。
widths[i] 值的范围在 [2, 10]。
简单题，代码如下:
class Solution {
public:
    vector<int> numberOfLines(vector<int>& widths, string S) {
        int line=1;
        int sum=0;
        for(auto c: S)
        {
            sum+=widths[c-'a'];
            if(sum==100)
            {
                line++;
                sum=0;
            }
            else if(sum>100)
            {
                line++;
                sum=widths[c-'a'];
            }
        }
​
        return vector<int>{line,sum};
​
    }
};
