Counting page numbers 0 ~ 9 The number of times the page appears, and the page number is 0.
The simplest method is to traverse each number in sequence, but this algorithm is too time-complex. If we use recursion, a large number of memory will pop up, and the time-space complexity will be high, which is intolerable.
Therefore, we have found a satisfactory method.
A random string that obtains the 0-9,a-z,a-z range
Copy Code code as follows:
/**

* @param length random number

The 0x65+0x66 in "window.event.keycode=0x65+0x66" represents the letter key number (mentioned above). The letter key must be indicated by the letter key number, cannot be indicated by the letter, otherwise the program will not recognize this key. The key value numbers for A~z, 0~9, and function keys are given below:
Key Name Key number keys number key
A 0x65 U 0x85
B 0x66 V 0x86
C 0x67 W 0X87

Title Description
Give an interval of a-B to count the number of occurrences in this interval of 0-9.For example, 10-19,1 appears 11 times (10,11,12,13,14,15,16,17,18,19, of which 11 includes 2 1), and the remaining numbers appear 1 times. Input
Two number A, a (1 Output

After the expression plus the parameter G, it indicates that a global match can be made, noting the meaning of "can" here. We describe in detail:1) for the Exec method of an expression object, without adding g, only the first match is returned, regardless of how many times it is executed, and if you join G, the firs
