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())
s = input()
l = len(s)
if l < k * a or l > k * b:
	print("No solution")
elif l == k * a:
	for i in range(k):
		print(s[:a])
		s = s[a:]
elif l == k * b:
	for i in range(k):
		print(s[:b])
		s = s[b:]
else:
	arr = [a] * k
	x = l - k * a
	i = 0
	while x != 0:
		arr[i] += 1
		x -= 1
		i += 1
		if i == k:
			i = 0
	for j in arr:
		print(s[:j])
		s = s[j:]
