Anfisa the monkey learns to type. She is yet unfamiliar with the "space" key and can only type in lower-case Latin letters. Having typed for a fairly long line, Anfisa understood that it would be great to divide what she has written into *k* lines not shorter than *a* and not longer than *b*, for the text to resemble human speech more. Help Anfisa.
The first line contains three integers *k*, *a* and *b* (1 ≤ *k* ≤ 200, 1 ≤ *a* ≤ *b* ≤ 200). The second line contains a sequence of lowercase Latin letters — the text typed by Anfisa. It is guaranteed that the given line is not empty and its length does not exceed 200 symbols.
k,a,b=map(int,input().split())
ss=input()
h=len(ss)
q,r=divmod(h,k)
if q<a or q>b or (q==b and r>0):
  print('No solution')
else:
  i=0
  while r>0:
    print(ss[i:i+q+1])
    r-=1
    i=i+q+1
  while i<h:
    print(ss[i:i+q])
    i=i+q
