1062. Calculate the Manhattan distance, 1062 calculate the Manhattan distance The question description shows the coordinates (x1, y1), (x2, y2) of the two points on the plane, and calculates the Manhattan distance between the two points. Manhattan distance = | x1-x2 | + | y1-y2 |. Enter the real numbers separated by four spaces in a row, representing x1, y1, x2, y2, respectively. Output a re

Calculate the length of the text, distinguish between Chinese and English characters, and calculate the length in Chinese. Public int text_length (string text){Int Len = 0; for (INT I = 0; I { If (byte_len.length> 1) Len + = 2; // If the length is greater than 1, it is Chinese and occupies two bytes, + 2 else Len + = 1; // If the length is equal to 1, it is English and occupies one

Why I write this program of $a+ $b and $a-$b can not calculate, other can calculate Ah, ask the big God solve!!! $a =$_request["NUM1"]; $b =$_request["num2"]; $fuhao =$_request["Fuhao"]; Class cat{ Public function Jisuan ($a, $b, $fuhao) { Switch ($fuhao) { Case "+": $a + $b; Echo ' $a + $b = '. $a + $b; Break Case "-": $a-$b; Echo ' $a-$b = '. $a-$b; Break Case "*": $a * $b; Echo ' $a * $b = '. $a * $b;

Function class $a =$_request["NUM1"]; $b =$_request["num2"]; $fuhao =$_request["Fuhao"]; Class cat{ Public function Jisuan ($a, $b, $fuhao) { Switch ($fuhao) { Case "+": $a + $b; Echo ' $a + $b = '. $a + $b; Break Case "-": $a-$b; Echo ' $a-$b = '. $a-$b; Break Case "*": $a * $b; Echo ' $a * $b = '. $a * $b; Break Case "/": $a/$b; echo ' $a/$b = '. $a/$b; Break } } } $cat 1=new Cat (); $cat 1->jisuan ($a, $b, $fuhao); ?> Reply to discussion (solution) It's working, you can

This question is so sad. I have been wa for a long time because I have misunderstood the question. Let's talk about how to solve the problem first: 1. When the two line segments do not want to be handed over, the result is 0.00. Parallel conditions are excluded here; 2. When either of the two line segments is parallel to the X axis, the result is also 0.00; 3. When the two line segments intersect but are in the same line (determined in parallel), the result is also 0.00; 4. Another situation is

If the current repayment date has not been paid off, the corresponding overdue interest will be generated, and the overdue interest shall be charged 0.05% per day for the unpaid amount of the present period. For example, October you want to return 10000 yuan, but before October 10, only 5000 yuan, on October 14 repayment, will generate overdue interest 10 yuan (formula: 5000 yuan x0.05%x4 days). In general, the overdue charges are also very low, at present the flower is rated at 3000 yua

Completely understand the IP address -- after computing the relevant IP address, you can calculate the IP address and subnet mask: 1. network address 2. broadcast address 3. Address range 4. Several hosts on this website. Example 1: in the following example, the IP address is 192 · 168 · 100 · 5. The subnet mask is 255 · 255 · 255 · 0.

IP address and subnet mask used for computing After knowing the IP address and subnet mask, you can calculate: 1. Network Address2. broadcast address3. Address range4. Several hosts on this website Example 1: the IP address in the following example is 192 · 168 · 100 · 5. The subnet mask is 255 · 255 · 255 · 0.

. 11111111 To convert the IP address to 0.0.0.255 in decimal format, we remove the 0 value on the left and leave only the number on the right. Therefore, the host number of this IP address is 255. The host number indicates that the IP address is added to the network number plus 255. 4. Calculate the broadcast address Also, use the formula: Based on the obtained network number, fill in 1 for all the binary bits of the host that represents the IP addres

. Also use MySQL's function Inet_aton (' 119.115.0.0 ') to derive an integer. In addition MySQL database field set four fields, starting IP, terminating IP, starting IP integer, terminating IP integer, How to calculate an IP address that is not assigned. Can MySQL be alone or mysql+php? Thank you very much please enlighten me. 119.115.0.0--119.115.255.255 Assign the following address 119.115.136.132,119.115.136.135 119.115.141.0,119.115.141.15 119.115

Sometimes it is necessary to calculate the execution time of the command, which can be used, although the time command can be accurate to the millisecond level, but it is not possible to calculate the execution times of a heap of commands. You can also use the date command to calculate the time difference before and after the execution of a command, but using the
