Answer 1

sentence = input()
N = int(input())
words = sentence.split()
lengths = [len(word) for word in words]
tempSentence = ''.join(words)
tempSentence = tempSentence[-N:] + tempSentence[:-N]
rotatedSentence = ''
letterCounter = 0
for letter in lengths:
    if rotatedSentence:
        rotatedSentence += ' '
    rotatedSentence += tempSentence[letterCounter:letterCounter+letter]
    letterCounter += letter


print(rotatedSentence)
