我正在研究一个问题,我要在数组中的所有沙漏中打印最大的总和.你可以在这里找到有关问题的详细信息-

我尝试了什么:

public class Solution {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int arr[][] = new int[6][6];
        for (int arr_i = 0; arr_i < 6; arr_i++) {
            for (int arr_j = 0; arr_j < 6; arr_j++) {
                arr[arr_i][arr_j] = in.nextInt();
            }
        }

        int sum = 0;
        int tmp_sum = 0;
        for (int arr_i = 0; arr_i < 4; arr_i++) {
            for (int arr_j = 0; arr_j < 4; arr_j++) {
                if (arr[arr_i][arr_j] > 0) …

我正在研究ROR网络应用程序.我的网页网址如下所示 -

http://dev.ibiza.jp:3000/facebook/report?advertiser_id=2102#/dashboard

在这里我理解advertiser_id是2102但我无法理解#/ dashboard指向的是什么？

我想使API调用类似于下面的curl命令:

curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer 
1djCb/mXV+KtryMxr6i1bXw" 
-d '{"operands":[]}' 
https://ads.line.me/api/v1.0/authority_delegations/get

我在想什么

public void send_deligation_request(String details[]) throws Exception{
    System.out.println(Arrays.toString(details));

    URL line_api_url = new URL("https://ads.line.me/api/v1.0/authority_delegations/get");
    String payload = "{operands:[]}";



    HttpURLConnection linec = (HttpURLConnection)line_api_url.openConnection();
    linec.setDoInput(true);
    linec.setDoOutput(true);
    linec.setRequestMethod("POST");
    linec.setRequestProperty("Content-Type", "application/json");
    linec.setRequestProperty("Authorization", "Bearer "+access_token);

    OutputStreamWriter writer = new OutputStreamWriter(linec.getOutputStream(), "UTF-8");
    writer.write(payload);


    BufferedReader in = new BufferedReader(
                            new InputStreamReader(
                                    linec.getInputStream()));
    String inputLine;

    while ((inputLine = in.readLine()) != null) 
        System.out.println(inputLine);
    in.close();
}

但我得到以下错误:

[naofumi.haida@torchlight.co.jp, 5514]

java.io.IOException: Server returned HTTP response code: 400 for …

我是Angular的新手.我正在研究配置块并运行模块块.

请看下面的代码:

angular.module('myModule', []).
config(function(injectables) { // provider-injector
// This is an example of config block.
// You can have as many of these as you want.
// You can only inject Providers (not instances)
// into config blocks.
}).
run(function(injectables) { // instance-injector
// This is an example of a run block.
// You can have as many of these as you want.
// You can only inject instances (not Providers)
// into run blocks
});

正如您在配置块中看到的那样,它写成:"您只能注入提供者(而不是实例)".

这是什么意思？谁能解释一下提供者和实例之间的区别是什么？

我很难弄清楚这里的用途是什么typedef-

typedef char TYPE_SSOSettingError;
typedef void (*ans_executeDomainRegistration) (TYPE_SSOSettingError);

从我理解的第一行TYPE_SSOSettingError定义为char.

从下一行我可以看出,这ans_executeDomainRegistration是一个指向函数的指针,该函数具有返回类型void并且char在这种情况下采用类型的参数TYPE_SSOSettingError

然后typedef在最后一行有什么用？
