You must have heard of an ancient encryption called Caesar
cipher or 'shift cipher'. That is, given the plaintext and a number D,
you should replace every character c in the plaintext with another
character which is D places after c in the alphabet. For example,
if D= 2, you should replace 'a' with 'c', replace 'b' with 'd', ...
replace 'y' with 'a', and replace 'z' with 'b'.
Given the plaintext and D, you should output the cipher text.
Input
The first line is an integer T, the number of test cases. Then Tcases follows.Each case contains only one line, consists of the plaintext and the number D, separated by a space. You can assume there are only lower case letters in the plaintext, and the length is no more than 100. 0 ≤ D < 26.
Output
Output one line for each test case, indicating the cipher text.
Sample Input
2 tjucs 1 abcd 0
Sample Output
ukvdt abcd
