 * When we want to insert two-dimensional data (like the entries of a grid that has coordinates in $x$ y $y$) in a one-dimensional array we use a formula to convert every coordinate $(x,y)$ to an index $i$ of the array. For every point with coordinates $(x,y)$ in the grid, we evaluate $i=(number-of-columns)*y+x$, where `number-of-columns` represents the width of the two-dimensional array, and the result $i$ will be the index of the one-dimensional array that corresponds to the point with coordinates $(x,y)$ in the grid. For example, the index $i$ that corresponds to the point $(1,2)$ in the grid of width $5$ is $i=(5)*2+1=11$.
