You are given a string S of length 3 consisting of a, b and c. Determine if S can be obtained by permuting abc.

Constraints

|S|=3

S consists of a, b and c.

Input

S

Output

If S can be obtained by permuting abc, print Yes; otherwise, print No.

No

Solution in Python (3.8.2) (judge verdict: Accepted)

s = input()
a = [0]*3
for i in s:
  if i=="a":
    a[0] += 1
  elif i == "b":
    a[1] += 1
  elif i =="c":
    a[2] +=1
 
if a[0]==a[1]==a[2] ==1:
  print("Yes")
else:
  print("No")
