TicTacToe

//You are given tic-tac-toe board (3 columns and 3 rows) like the one the right. As inputs you will be given the X and Y coordinates of one of the cells. Each of the cells in the field has an index and a value (look at the examples on the right). You will be given the value of the first cell V (index1). Each of the next cells will have value greater by 1 than the previous. Example: if value=80, then index1=80, index2=81, index3=82, ..., index9=89. Your task is to print on the console the value of the cell C raised to the power of its index: C index. Look at comments in the examples below to understand your task better.
//Input
//The input data should be read from the console.
//•   At the first line you will be given the X coordinate.
//•   At the second line you will be given the Y coordinate.
//•   At the third line an integer number V will be given, specifying the value of the first cell.
//The input data will always be valid and in the format described. There is no need to check it explicitly.
//Output
//The output should be printed on the console. It should consist of 1 line:
//•   Print the value C of the cell at position {X, Y} raised to the power of its index.
//Constraints
//•   The X and Y inputs will be integers in the range [0…2].
//•   The V input will be an integer in the range [0…100].
//•   Allowed working time: 0.2 seconds. Allowed memory: 16 MB.
