1) Maximum approximate problem:For a given two positive integers, a, B, computes the number of approximately several numbers between a and a. For example: between a=1,b=36,1 and 36, the maximum number is 36, and the number is 9.Idea: The common method is to cycle tests between A and B each number exactly how many appro

The default initialization mechanism of the. NET system sets all objects to 0 [14]. We cannot block other value types.ProgramMembers Initialize all their members to 0 [15]. Therefore, we should use 0 as the default value of the value type.
Enumeration is a typical case. The enumerated type we created should never reg
Valid tive C # Item 8: ensure that 0 is a valid state for value types
In. net, all object information is set to 0 by default during initialization. For value types, we cannot avoid setting the value to 0 when creating a new value type instance. This

. When the matching circuit parameters are uncertain, use 0 ohm instead. In actual debugging, determine the parameters and replace them with specific resistance values.
4. When you want to test the current of a line, you can remove the 0 ohm resistance and connect it to the current meter to facilitate the test.

This article mainly introduces php's method of auto-complementing 0 when the card number is not enough based on str_pad, which is very useful for generating fixed-digit numbers, if you need it, you can refer to the str_pad function in php to automatically fill up the white space. the str_pad () function can help us implement it. the str_pad () function fills the
The str_pad card number is used by php to automatically fill in the number of digits below the number of digits based on str_pad. Php uses the str_pad method to automatically add 0 digits when the card number is insufficient. the str_pad function can help us implement the str_pad function in php () the function fills the string in php. based on str_pad, the funct
Describes the comparison between a method of a string and a property to determine whether a string variable is empty, a string variable ' s ', and the following expression is faster?
1. String.IsNullOrEmpty (s)
2. S = = NULL | | s.length = 0
If you guess the second one, then you're right. It will be 15% faster than the String.IsNullOrEmpty method, but this
. Net will set the object value to 0 by default. For the value type, for example, struct, we cannot prevent developers from setting the members in the struct to 0. Therefore, we need to set 0 to the valid state.
For an enumeration type, if you create an enumeration type object using the new method, the object value is

By default, if the number of digits entered in the current cell in Excel is more than 11 digits (excluding 11-bit), the system displays the numbers entered in the scientific notation format, and when the number of digits entered exceeds 15 digits (excluding 15-bit), the system displays all 15-digit numbers as "
