In the popular spreadsheets systems (for example, in Excel) the following numeration of columns are used. The first column has A number A, the Second-number B, etc. till column, which is marked by Z. Then there was Two-letter Numbers:column have number AA, 28-ab, column is marked by AZ. After ZZ there follow three-letter numbers, etc.
The rows is marked by an integer numbers starting with 1. The cell name is the concatenation of the column and the row numbers. For example, BC23 are the name for the cell, which is in column, row 23.
Sometimes another numeration system is used:rxcy, where X and Y are integer numbers, showing the column and the row Numbe RS respectfully. For instance, r23c55 are the cell from the previous example.
Your task is to write a program this reads the given sequence of cell coordinates and produce each item written according To the rules of another numeration system. Input
The first line of the input contains integer number n (1≤n≤105) and the number of coordinates in the test. Then there follow n lines, each of the them contains coordinates. All the coordinates is correct, there is no cells with the column and/or the row numbers larger than 106. Output
Write n lines, each of the line should contain a cells coordinates in the other numeration system. Sample Test (s) input
2
r23c55
BC23
Output
BC23
R23c55
There are two representations of a grid, one is the r***c*** form, the other is the letter + number form, and two conversion relationships can be seen in the sample;
