How many positive integers less than 211 are relatively prime to 126? How many ternary (0, 1, 2) sequences of length 10 are there without any consecutive digits the same?Peb 16, 2023 — Given a range [L, R], the task is to count the numbers which have even number of odd digits and odd number of even digits. For example, 8 has 1 even digit and 0 odd digit - Satisfies the condition since 1 is odd and 0 is even.545 has 1 even digit and 2 odd digits - Satisfies the condition since 1 is odd and 2 is even.4834 has 3 even digits and 1 odQ2: Observe that the only possibilities for the last digit that will make the number odd are $1,3,5,7,9$. Once you pick this digit, there will be $9-1=8$ remaining possibilities for the first digit. Once you pick these two digits, there will be $10-2=8$ remaining possibilities for the second digit.
