a <= b <= c <= d
b+c = 11
so, since b<=c, b=1 c=10
so, b+c is odd, a+d is even, and
since b=1, a=1 since a <= b
if a+d is even, is odd and the coins are
1 1 10 25
since 10 <= d
b+c = 11
so, since b<=c, b=1 c=10
so, b+c is odd, a+d is even, and
since b=1, a=1 since a <= b
if a+d is even, is odd and the coins are
1 1 10 25
since 10 <= d
