One day while taking a break in industry, you notice a random pattern of blue and green tiles on the floor.

Reminiscing about happier times in ITEC$2620,$ you decide to write a recursive

function that will determine how many more blue tiles there are than green tiles.

To develop this function, assume that the color of each tile is stored in a fully populated character array. In this array, a $\text{'}$B$\text{'}$ will represent a blue tile, and a $\text{'}$G$\text{'}$ will represent a green tile.

For example, calling your moreBlue $()$ function on the following array

tileArray

B

G

B

B

G

G

B

G

will return $-2.$

Example $1$:

In particular, the following statements would lead to the underlined output:

York, printin more Blue tile Array, tile Array.length$-1,0))$:

Example $2$:

char$[]$ ar $=$ new charl $\{\text{'}$B$\text{'},\text{'}$B$\text{'},\text{'}$G$\text{'},\text{'}$G$\text{'},\text{'}$B$\text{'}\}$;

York.printIn$($ moreBlue$($ar$,$ ar$.$length$-1,0))$;
