Idea: If we were to fill 0 in front of the number , we would find that the N-bit all 10 binary number is actually N from 0 to 9 of the full array. That is to say, we arrange each digit of the number from 0 to 9, and we get all the 10 binary numbers. 1 /**2 *ch Storing numbers3 *n n Number of digits4 *index Count Value5

1. Question Given a random number generator, this generator can generate a random number ranging from 1 to 5 () evenly. How can we use this generator to generate a number ranging from 1 to 7? 2. Ideas Method 1: generate two (1, 5) random numbers. In this case, there are 25 random numbers. Note that these two numbers are sequential. In these 25 cases, take the

(1) method to determine whether a number is the multiplication of 2: For the integer num, if (Num (num-1) = 0, then this number is the multiplication of 2. The procedure is as follows: Public class test {Public static void main (string [] ARGs ){System. Out. println (issqure (512); // equivalent to test. issqure ()}Public static Boolean issqure (INT num) {// This method must use the static keyword, because

Combine the four digits in the middle of the phone number into a Number * and four digits into a number. MySql APIs have functions: INSERT (str, pos, len, newstr) Returns the str string. Its substring starts from the pos position and is long replaced by the string newstr. If the pos length exceeds the string length, the return value is the original st

From 1 to 9, the nine digits form a nine-digit number with no duplicates. If a number is extracted from the left, it must be divisible by 1. The number composed of two numbers can be divisible by 2. The number composed of three numbers can be divisible by 3, and so on... The number
