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:
0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ$%*+-. /:
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 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 apace which is then followed by the new string T,which is made of each character in S repeated R times.
