Misha and Vasya participated in a Codeforces contest. Unfortunately, each of them solved only one problem, though successfully submitted it at the first attempt. Misha solved the problem that costs *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 <img align="middle" class="tex-formula" src="https://espresso.codeforces.com/e7bb7983e9c15baf66651c7643406c249354c8c1.png" style="max-width: 100.0%;max-height: 100.0%;"/> points. 

Misha and Vasya are having an argument trying to find out who got more points. Help them to find out the truth.
The first line contains four integers *a*, *b*, *c*, *d* (250 ≤ *a*, *b* ≤ 3500, 0 ≤ *c*, *d* ≤ 180). 

It is guaranteed that numbers *a* and *b* are divisible by 250 (just like on any real Codeforces round).

m1,v1,tm1,tv1 = input().split()
m1,v1,tm1,tv1 = int(m1),int(v1),int(tm1),int(tv1)

m2 = int(m1-((m1/250)*tm1))
v2 = int(v1-((v1/250)*tv1))
m3 = int((3*m1)/10)
v3 = int((3*v1)/10)

mm = max(m2,m3)
vv = max(v2,v3)

if mm > vv:
    print("Misha")
elif mm < vv:
    print("Vasya")
else:
    print("Tie")
