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.

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;
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
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
