rustRust negative for loop example

Negative for loops in Rust are used to iterate over a range of numbers in reverse order. The syntax for a negative for loop is similar to a regular for loop, but the range is specified with a .rev() method.

Example code

for i in (0..10).rev() {
    println!("{}", i);
}

Output example

9
8
7
6
5

0

Code explanation

• for i in (0..10).rev(): This is the loop syntax, which specifies the range of numbers to iterate over. The .rev() method reverses the range, so the loop will start at 10 and end at 0.
• println!("{}", i): This is the code that will be executed for each iteration of the loop. In this case, it prints the current value of i to the console.
