Python converts a string to a number using reduce and map. Introduction to reduce and map in python map(func,seq1[,seq2...]) : Function func is used to act on each element of a given sequence, and a list is used to provide the return value. If func is None, func is represented as an identity function, returns a list of n tuples containing the collection of elements in each sequence. reduce(func,seq[,init])
noted that the first number of outputs cannot have a leading 0, and if all the numbers are 0, we can only output one 0.For these two requirements, I used StringStream to convert the string to a number.For the first number, just switch directly to the digital output.In order to determine whether all the numbers are 0,

A specific value can be accessed using a coercion type conversion, even if it is of a different type.The 3 types of coercion conversions available in ECMAScript are as follows:Boolean (value)-converts the given value to a Boolean type;Number (value)-converts the given value to a digit (which can be an integer or a floating point);String (value)-converts t
PHP is easy to ignore and error trap numbers are compared with strings. 0 returns true if it is compared with any character leading by a non-number (or character that cannot be converted to a number) (operator. the reason is that when comparing numbers with strings, first try to convert strings 0 returns true if it is compared with any character leading by a non-

In SQL Server, the software version number is compared to the character string. in SQL, the version numbers such as 1.2.1.571.2.12.57 are compared directly. In this case, a downconversion is required to convert 1.2.1.57 to 00001000020000100057 for comparison. [fun_split_version] is used for comparison. createfunction [dbo].
