### Question regarding pythagorean triplets

Does 2mn>m2-n2 always hold?
Do m,n belong to natural numbers?

### Re: Finding permutations of any 3-digit number

Yeah! That's what I was exactly going to suggest before I saw your post. And now I've solved my problem. Did the following - seq={ones_digit,tens_digit,hundreds_digit} for (int i=0;i<=2;i++) Output seq[i], seq[(i+1)%3], seq[(i+2)%3] Output seq[i], swap(seq[(i+1)%3],seq[(i+2)%3]) //Where 'swap' wi...

### Finding permutations of any 3-digit number

Now I was working on this problem in school where I had to list out all possible permutations of a given three digit number. Here's my code - Output "Enter a three-digit number: " Input no hundreds_digit=no/100, ones_digit=no%10, tens_digit=no/10-10*hundreds_digit Now I've got the one's, ten's and t...
