##输入格式##
The first line of input contains a single integer P, (1 &lt= P &lt= 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 &lt= R &lt= 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.
