Have you heard about "down-to" operator?

Let's make it interesting! Suppose you're given a program to print all numbers from m to n. Easy, isn't it? Check out the following code which uses the "down-to" operator for this purpose: https://code.sololearn.com/c9iEFTCXyooP/#cpp But, there is something "irony" in this "down-to" operator... Can you resolve it?

@Sai welcome! Even I myself had no idea. Actually, it's not just in C++ only, it's also in Java, JS and other popular languages, EXCEPT Python... Can you guess why?

😀Good joke. The irony is this "operator" actually down-to to 0, not 1

@Sai Actually the "-->" thing isn't actually an operator. It's a combo of "--" and ">". Line 8th in my code can be illustrated as: } while ( (a--) > 1 ); And, the loop will runs until a equals 1, i.e., "a goes to 1" ;) This is the reason why there is no docs on this operator in any language. LOL!
