写一个函数，输入参数有四个，分别是map<string,float>型数据，整数，float型数组,string型数组。返回结果，将map中的数据按float值进行排序，并将排序后的结果保存到float、string两个数组中，两个数组元素必须对应于map数据。-Write a function, there are four input parameters, are the map <string,float> data, integer, float array, string array. Return results in the map data according to the float value to be sorted, and sorted the results saved to a float, the string array, the array elements must correspond to the map data.
