Answer:
The solution code is written in Java.
Explanation:
Firstly, we need to create an array to hold a list of letters (Line 6). In this solution, only letters A - J are given for simplicity.
Next, we declare all the variables that we need, numRows, numColumns, currentRow and currentColumn (Line 8 - 11).
Next, we use Scanner object, scnr to prompt user to input integer for numRows and numColumns (Line 12-13).
At last, we use two-layer for loops to traverse through the number of rows and columns and print out the currentRow and currentColumn (Line 15-19). Please note the currentRow is added by 1 as the currentRow started with 0. To print the letter, we use currentColumn as an index to take out the letter from the array.
