Sample Input 1

Q142857Z

Sample Output 1

Yes

S is a concatenation of Q, 142857, and Z in this order.
Q and Z are uppercase English letters, and 142857 is a string of length 6 that is a decimal representation of an integer between 100000 and 999999, so S satisfies the condition.

Sample Input 2

AB912278C

Sample Output 2

No

AB is not an uppercase English letter, so S does not satisfy the condition.

Sample Input 3

X900000

Sample Output 3

No

The last character of S is not an uppercase English letter, so S does not satisfy the condition.

Sample Input 4

K012345K

Sample Output 4

No

012345 is not a string of length 6 that is a decimal representation of an integer between 100000 and 999999, so S does not satisfy the condition.
