,Because, 1229> 168, 1229-168 × 7 = 53, is the number of requests.Example 3: divide a number by 5 plus 4, divide by 8 plus 3, and divide by 11 plus 2 to obtain the minimum natural number that meets the conditions.The numbers 5, 8, and 11 are mutually qualitative.Then [8, 11] = 88; [5, 11] = 55; [5, 8] = 40; [5, 8, 11] = 440.In order to make 88 be divided by 5 and 1, 88 × 2 = 176 is used;So that 55 is divided by 8 and 1, with 55 × 7 = 385;So that 40 is divided by 11 and 1 is used, 40 × 8 = 320.Th

Because table t1 records are very small as a driving table and table t has indexes, it is suitable for NL. The execution plan is as follows:
SQL> set wrap off;SQL> set autotrace traceonly;
SQL> select a. table_name, B. table_name from t a, t1 B2 where a. table_name = B. table_name;
Eight rows have been selected.

, 11] = 88; [5, 11] = 55; [5, 8] = 40; [5, 8, 11] = 440. In order to make 88 be divided by 5 and 1, 88 × 2 = 176 is used;So that 55 is divided by 8 to 1, with 55 × 7 = 385; so that 40 is divided by 11 to 1, with 40 × 8 = 320. Then, 176 × 4 + 385 × 3 + 320 × 2 = 2499. Because, 2499> 440, 2499-440 × 5 = 299 is the desired number.

Console.trace () to better demonstrate this behavior, and it will print out records from the current stack on the console. In addition, you should generally read stack records from top to bottom. Think about where each of the following lines of code is invoked. Function C () {Console.log (' C '); Console.trace ();} Function B () {Console.log (' B '); C ();} function A () {Console.log (' a '); B ();} A (); Running the above code on the node REPL server will getThe following results: Trace at C (

Two Chinese characters, one symbol or number, and one English character are counted. (If it is set to 140 words, multiply by 2, then it is 280 words ). You need to use the Math. ceil method, because the number of words displayed to the user must be restored by dividing the last two. One Chinese character is counted as two, one symbol or number, and one English character is counted as one. (If it is set to 140 words, multiply by 2, then it is
