# You are given a string that consists of letters a–z and digits 1–9.
# The following operation is repeated, until there are no digits left in the
# string:
# Find the leftmost digit, 1 \le d \le 9. Depending on its value, duplicate the
# substring of length d on the right side of the digit. After this, delete the
# digit from the string.
# For example, for the string 82silisko, the operations proceed as follows:
# 82silisko \rightarrow 2silisko2silisko \rightarrow sisilisko2silisko
# \rightarrow sisiliskosisilisko
# Find what the string will be after the operations. You can assume that the
# string eventually only contains letters.
# Input
# The only line of the input is a string consisting of characters a–z
# and 1–9.
# Each digit d is followed by at least d more characters.
# Output
# Output the string after the operations.
# Example 1
# Input:
# 82silisko

# Output:
# sisiliskosisilisko
# Example 2
# Input:
# mis3si1pi

# Output:
# mississippi


# let's brute force
