Every time the compiler shows me this Array Index Out Of Bounds and shows me in the witch line i have error but i just don't get it how to fixed it and why compiler printing me this mistake because there is enough space in array field[][] because i provided a n+2 X s+2 fields in array and i am using just 1 to n ,including and 1 to s ,including m, so i have not used fields from field[0][0] to field[0][s+1] and field[0][0] to field[n+1][0], field[n+1][0] to field[n+1][s+1] ,field[n+1][s+1] to field[0][s+1] ,so i suppose i can check their values and do not get out of array bounds,but compiler claims otherwise!!!
