Question 1: focal length time limit: 256 ms single point time limit: Ms memory limit: MB
Description
In general, we use a pinhole camera model, that is, we think it uses the principle of small hole imaging.
In the camera coordinate system, in general, the unit length we use is not an international unit such as "meter", but the length of adjacent pixels. The focal length in the camera coordinate system is an important physical quantity in the field of image processing.
If we have obtained
Infrared has always brought me a lot of mysterious yearning, different bands, different weather, different materials to shoot out different colors. It is a challenge to use infrared photography as a portrait, but how to adjust for such a film later?

. An example of PHP's automatic conversion of variable types is the addition operator '+ '. If any operand is a double-precision number, all operands are evaluated as double-precision numbers, and the result is also a double-precision number. Otherwise, the operand is considered an integer, and the result is also an integer. Note that this does not affect the variable type of each operand. the only change is how the operand is processed during calculation. $ Foo = "0"; // $ foo is a string with
addition. If any one operand is a double-precision number, then all operands are evaluated as double-precision numbers, and the result is a double-precision number. Otherwise, the operand will be considered an integer and the result will be an integer. Note that this does not affect the variable type of each operand itself, and the only change is how the operand is handled during the calculation. $foo = "0"; $foo is a string with a value of "0" (ASCII 48)

The code is as follows$foo = "
