如何将数字转换为字符串集合

def number_to_string_set(number):
    string_set = set()
    for i in range(1, number + 1):
        string_set.add(str(i))
    return string_set

import java.util.HashSet;
import java.util.Set;

public class NumberToStringSet {
    public static Set<String> numberToStringSet(int number) {
        Set<String> stringSet = new HashSet<>();
        for (int i = 1; i <= number; i++) {
            stringSet.add(Integer.toString(i));
        }
        return stringSet;
    }
}

function numberToStringSet(number) {
    const stringSet = new Set();
    for (let i = 1; i <= number; i++) {
        stringSet.add(String(i));
    }
    return stringSet;
}

using System;
using System.Collections.Generic;

public class NumberToStringSet {
    public static HashSet<string> NumberToStringSetMethod(int number) {
        HashSet<string> stringSet = new HashSet<string>();
        for (int i = 1; i <= number; i++) {
            stringSet.Add(i.ToString());
        }
        return stringSet;
    }
}
