Why to use extra space / variable?

#1

public static void triangleEqualReverseRN(int n) {
int rows = 1;
while (rows <= n) {
int col = 0;
while (col <= n - rows) {
System.out.print("* ");
col++;
}
System.out.println();
rows++;
}
}

@nikhar_ae513f1ea7b43118 Re : Logic of the code varies from person to person. So if you’re able to get the answer by using fewer variables then it’s a good thing and you don’t need to use that extra variable.
