Translate the pseudocode in Section 2.4 for computing the number of tiles and the gap width into Java.

number of pairs = integer part of (total width - tile width) / (2 x tile width)number of tiles = 1 + 2 x number of pairsgap at each end = (total width - number of tiles x tile width) / 2

I'm wondering why this test failed, during another test, it was good because the gap was 1.00. Is there something I should do in terms of rounding?

... 7. Translate the pseudocode in Section 2.4 for computing the number of tiles and the gap width into Java.
number of pairs
number of tiles = | + 2 x number of pairs
integer part of (total width - tile width) / (2 x tile width)
gap at each end
= (total width - number of tiles x tile width) / 2

int totalWidth = in.nextInt ();
System.out.print ("Tile width: ");
int tileWidth = in.nextInt();
int pairs = (totalWidth - tilewidth) /(2 * tileWidth);
int tiles= 1 + (2 * pairs);
double gap = (totalWidth - (tiles * tileWidth))/2;
System.out.printf("Pairs: %d%nTiles: %d%nGap:
