output

a points and Vasya solved the problem that costs b points. Besides, Misha submitted the problem c minutes after the contest started and Vasya submitted the problem d minutes after the contest started. As you know, on Codeforces the cost of a problem reduces as a round continues. That is, if you submit a problem that costs p points t minutes after the contest started, you get

 points.

Misha and Vasya are having an argument trying to find out who got more points. Help them to find out the truth.

Input

a, b, c, d (250 ≤ a, b ≤ 3500, 0 ≤ c, d ≤ 180).

a and b are divisible by 250

Output

Output on a single line:

Misha" (without the quotes), if Misha got more points than Vasya.

Vasya" (without the quotes), if Vasya got more points than Misha.

Tie" (without the quotes), if both of them got the same number of points.
