  • 问题描述
  • For this problem, you will write a program that takes a string of characters, S, and creates a new string of characters, T, with each character repeated R times. That is, R copies of the first character of S, followed by R copies of the second character of S, and so on. Valid characters for S are the QR Code "alphanumeric" characters:
  • 输入
  • The first line of input contains a single integer P, (1 <= P <= 1000), which is the number of data sets that follow. Each data set is a single line of input consisting of the data set number N, followed by a space, followed by the repeat count R, (1 <= R <= 8), followed by a space, followed by the string S. The length of string S will always be at least one and no more than 20 characters. All the characters will be from the set of characters shown above.
  • 输出
  • For each data set there is one line of output. It contains the data set number, N, followed by a single space which is then followed by the new string T, which is made of each character in S repeated R times.
