Smallest square that begins with n

Smallest square that begins with n 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 smallest squares that begin with n for 0 < n < 50

Ring

<lang ring> load "stdlib.ring"

see "working..." + nl see "smallest squares that begin with n:" + nl

row = 0 limit1 = 49 limit2 = 45369

for n = 1 to limit1

   strn = string(n)
   lenn = len(strn)
   for m = 1 to limit2
       floor = sqrt(m)
       bool = (m % floor = 0)
       strm = string(m)
       if left(strm,lenn) = n and bool = 1
          row = row + 1
