806. Number of Lines To Write String

static int wing=[]()
{
    std::ios::sync_with_stdio(false);
    cin.tie(NULL);
    return 0;
}();

class Solution 
{
public:
    vector<int> numberOfLines(vector<int>& widths, string S) 
    {
        int count=1,length=0;
        for(char c:S)
        {
            int cur=widths[c-'a'];
            if(cur+length<100)
            {
                length+=cur;
                continue;
            }
            else if(cur+length==100)
            {
                count++;
                length=0;
            }
            else
            {
                count++;
                length=cur;
            }
        }
        return {count,length};
    }
};

直接扫描，统计长度就行，问题不大
