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=[int(i)for i in input().split()]
s=input()
if k*b<len(s) or k*a>len(s):
    print('No solution')
else:
    n=a
    #c=len(s)//n
    while (len(s)//n)>=k:
        n+=1
    if (len(s)//n)<k:
#        if len(s)%n<a:
        h = 0
        l = n
        for i in range((len(s) // n) - 1):
            print(s[h:l])
            h += n
            l += n
        l=h+(k+(len(s)%n))//2
        print(s[h:l])
        h+=l-h
        print(s[h:])
