There are many formulas for calculating pi pai in history, in which Gregory and Leibniz found the following formula:
Pai = 4* (1-1/3+1/5-1/7 ...)
The formula is simple and graceful, but in a bad way, it converges too slowly.
If we rounded to keep its two decimal digits,

1. What is a set of operations: a set represents the sum of "various" things in mathematics. Indicates a set of records in the database field. Set operation: the set operation is the addition, subtraction, and other four operations on records meeting the same rule. Ii. Addition of tables -- Union addition operation union Union
Union and other set operations usually remove Repeated Records. Iii. Considerations for Set Operations
I use this statement in phpMyAdmin to bring up 7 results, but in the program it becomes 1.
SELECT Fcj.fang_time, Fcj.area, Fcj.taoshu from F_chengjiao as FCJ left JOIN F_city as FC USING (city_id) WHERE fcj.city_i D=1 ORDER by Fcj.fang_time LIMIT 0, 7

Main Code:
Static void main (string [] ARGs)
{
Int A = 49;
Int [] array = new int [49];
// Add the number to array
For (INT I = 0; I

Array [I] = I + 1;
}
// New a random number
Random random = new random ();
// Create the subscript of a random number
Int index;
Int temp;
For (INT I = 48; I> = 0; I --)

int rand7() { return rand()%7+1; } int rand10(){ int x=0; do { x=(rand7()-1)*7+rand7(); } while(x>40); return x%10+1;}

We know that a function f can obtain a random number ranging from 1 to 5 with equal probability. How can we obtain a random number ranging from 1 to 7 with equal probability?
Int rand7 (){Int;While (A = rand5 () * 5 + rand5 ()> 26 );Return (A-3)/3;}
AlgorithmThe idea is:1. Use rand5 () * 5 + rand5 () to generate 6
Random Number problem-it is known that there is a Random7 () function, returns a random natural number from 1 to 7, so that the Random7 () is used to construct a random 1 ~ Random10 ~ 10. random7random10
