Duplicated imports "toRef", the one from "vue" has been ignored and "@vueuse/core" is used

这是一个关于Vue.js中重复引入模块的警告信息。它表示在你的代码中有两个或更多相同的模块被引入了。在这种情况下，Vue.js会忽略掉前面已经引入的模块，而使用后面的那个模块。

对于这个特定的警告信息，它表示你在代码中同时引入了"vue"和"@vueuse/core"这两个模块，并且这两个模块中都定义了名为"toRef"的变量或函数。在这种情况下，Vue.js会忽略掉前面引入的"vue"模块中的"toRef"，而使用后面引入的"@vueuse/core"模块中的"toRef"。

解决这个问题的方法是去掉其中一个模块的引用，或者通过重命名其中一个模块中的"toRef"来避免命名冲突。

Duplicated Numbers 分数 10 作者 翁恺 单位 浙江大学 This program reads a lot of integers, in which may be duplicated numbers. The program picks out all the duplicated ones and sorts the remainders in a descendent order. 函数接口定义： public static ArrayList<Integer> pick(ArrayList<Integer> a); a is the ArrayList to be parsed and returns the result as an ArrayList. Hint: These classes and functions may be used.

To solve this problem, you can use a HashMap to store the frequency of each number in the ArrayList. Then, iterate through the HashMap to find the numbers that occur more than once and add them to a new ArrayList. Finally, sort the new ArrayList in descending order using Collections.sort() with a custom comparator.

Here's an implementation:

import java.util.ArrayList;
import java.util.Collections;
import java.util.HashMap;
import java.util.Map;

public class DuplicatedNumbers {
    public static ArrayList<Integer> pick(ArrayList<Integer> a) {
        HashMap<Integer, Integer> frequencyMap = new HashMap<>();
        for (int num : a) {
            frequencyMap.put(num, frequencyMap.getOrDefault(num, 0) + 1);
        }

        ArrayList<Integer> duplicatedNumbers = new ArrayList<>();
        for (Map.Entry<Integer, Integer> entry : frequencyMap.entrySet()) {
            if (entry.getValue() > 1) {
                duplicatedNumbers.add(entry.getKey());
            }
        }

        Collections.sort(duplicatedNumbers, (a1, a2) -> a2 - a1);
        return duplicatedNumbers;
    }
}

Duplicated key 'favoriteCount' vue/no-dupe-keys

This warning message is from Vue.js and it indicates that the same key has been used multiple times in a Vue.js template. Each element in a Vue.js template should have a unique key attribute.

To fix this warning, you need to go through your Vue.js template and make sure that each element has a unique key attribute. If you have multiple elements with the same key attribute, you can either remove the duplicates or make the key attribute unique by appending a unique identifier to it.

For example, if you have two elements with the key attribute "favoriteCount", you can rename them to "favoriteCount1" and "favoriteCount2" to make them unique.

Once you have fixed the duplicate key issue, the warning message should disappear.
