Functions with 2D Arrays in Java
Write a function named displayElements that takes a two-dimensional array, the size of its rows and columns, then prints every element of a two-dimensional array. Separate every row by a new line and every column by a space.
In the main function, call the displayElements function and pass in the required parameters.

- CODE USING C++ 3. Find the Culprit by CodeChum Admin "Help!!!" Someone's calling for help! It seems that someone was robbed and their phone was stolen. Luckily, the phone's GPS is turned on so we can track the culprit's coordinates! Instructions: Ask the user for the number of rows and columns of a 2D array and then its elements. Then, ask the user for another integer value which represents the culprit. Finally, go through the 2D array and find the culprit's coordinates - its row number and column number and display them. Input 1. Number of rows 2. Number of columns 3. Elements of the 2D array 4. Culprit's value Output Print the row of the position first and then the column of the position. Note that the row and the column is 0-based (i.e. it starts at 0 and not at 1). It is guaranteed that the culprit exists only once in the 2D array.
