conditional
statement
The input
number can be negative. The number n is two-digit if
-99 ≤ n ≤ -10
or 10 ≤ n ≤ 99
Algorithm
implementation
Read the input value of n.
scanf("%d", &n);
Print the answer.
if ((n > -100 && n <
-9) || (n > 9 && n < 100)) puts("Ok");
else puts("No");
Python implementation
Read the input value of n.
n = int(input())
Print the answer.
if (-100
< n < -9) or
(9 < n < 100): print("Ok")
else: print("No")
