Network Cell number host number
The first example: known ip:192.169.20.50 subnet mask: 255.255.255.224 to seek network cell number host number.
First, the subnet mask 255.255.255.224 is converted to bits
255.255.255.224:11111111.11111111.11111111.11100000
You can see that the left side of this mask is the same as the

We can also use random numbers to design any program structure that we imagine.
First, let's meet the random number function rand () provided by PHP. The rand () function of PHP returns a random integer, using the following method
Rand (Min,max)
The optional parameter min and Max allows rand () to return a pseudo-random integer between 0 and Rand_max. For example, want a random number between 5 and 15 (incl

Title: Counts the number of occurrences of a number in a sorted array. For example input sort array {1,2,3,3,3,3,4,5} and number 3, because 3 appears in this array 4 times, so output 4.The time complexity of the method of violence is O (n), there is a better solution, the use of binary search, the time complexity of O (LOGN):1. First to find the first occurrence
Number of occurrences of 1 in positive numbers from 1 to n
Topic:
Enter an integer n to find the number of occurrences of 1 in the decimal representation of the n integers from 1 to n.
For example, input 12, from 1 to 12 of these integers contains 1 of the number 1, 10, 1 1 and 12, 11 of which have occurred 5 times

DescriptionThe number of all combinations of n (n ≤ m) elements taken from m different elements is called the number of combinations of n elements taken from m different elements. The formula for calculating the number of combinations is as follows:C (m, n) = m!/((m - n)! N!)Now, if you write the combined number C (m,
