Search for substring in two dimensional array

 Save the string “WELCOMETOZOHOCORPORATION” in a two dimensional array and search for substring like “too” in the two dimensional string both from left to right and from top to bottom.

W E L C O
M E T O Z
O H O C O
R P O R A
T I O N   

And print the start and ending index as

Start index : <1,2>

End index: <3, 2>
