Find square difference

Find square difference is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Task

Find an show on this page the least integer number n, where diffrence of n*n and (n-1)*(n-1) greater than 1000

>br>The result is 5001 because 501*501 - 500*500 = 251001 - 250000 = 1001 > 1000

Ring

<lang ring> load "stdlib.ring" see "working..." + nl limit1 = 6000 limit2 = 1000 oldPrime = 0 newPrime = 0

for n = 1 to limit1

   newPrime = n*n
   if newPrime - oldPrime > limit2
      see "Latest number is = " + sqrt(newPrime) + nl
      exit
   ok
   oldPrime = n*n

next

see "done..." + nl </lang>

Output:

working...
Latest number is = 501
done...
