Questions: A merchant needs to ride a donkey across a 1000-kilometer desert to sell 3000 carrots. It is known that a donkey can carry 1000 carrots at a time, but it will eat 1 carrot every 1 kilometer. Q: How many carrots can a merchant sell at most? The solution of using a program here is actually very simple without a program: Program description: Both return and return are consumed. The maximum consump

Why is 1000==1000 in Java false and 100==100 true?This is a very interesting discussion topic.If you run the following code:Basic knowledge: We know that if two references point to the same object, = = to indicate that they are equal. If two references point to different objects, use = = to indicate that they are not equal, even if their contents are the same.Therefore, the following statement should also b

1000 in the hearts of 1000 HamletIt's a quote from Shakespeare.I feel like the Chinese dream of a red chamber, easy to learn to see the shallow, the Taoist family see is kinky, the Neo-Confucianism see is the inverse, the philosopher sees is chaos, the Prosodic scholar sees is mixed, the writer sees is full. Sociologists see is short. Each person's position is different from the feeling.This is Shakespeare'

Python _ does not need to print 1-1000 cyclically, and python prints 1-1000Question: I can print the 1000 numbers from 1 to on the screen. Do not use cyclic or conditional statements. Do not use them? : Operator. You are not allowed to use the method of listing output statements in the source code. For example, if you cannot use one thousand print statements, you will not repeat other silly behaviors. Answe

You can write less regular expressions of 1000 lines of code and 1000 rows of regular expressions. Mastering regular expressions can greatly improve your development efficiency. Regular Expressions are often used for field or any string verification. For example, the following section verifies the JavaScript code of the basic date format: var reg = /^(\\d{1,4})(-|\\/)(\\d{1,2})\\2(\\d{1,2})$/;var r = fieldV

Enter a positive number less than zero from the keyboard , which requires the output of its square root (if the square root is not an integer, output its integer portion). Requires that the data be checked for a positive number that is less than zero after it is entered . If not, a re-entry is required. Solution: Program:#include #include #define M 1000int main (){int x, y;printf ("Please enter a positive number less than%d x:", M);scanf ("%d", x);while (X>M){printf ("Input data does not meet

When a normal user enters the system, sometimes they need to switch the root user, and then change the normal user rights to root user rights. Then, when you are ready to enter the system again, the discovery can only be entered as guest. So find a variety of ways to change back, the following is the solution I encountered the situation: 1. Restart Ubuntu, press and hold shift to enter the Grup menu, or wait for the Grup menu to appear. 2. Select the Recovery Mode menu and press E to edit. 3
