.$$ solution: $$ (A, b) = 1\rightarrow (a^2, b) = 1 \rig Htarrow (a^2 + b^2, b) = 1.$$ similarly available $ (a^2 + b^2, a) = 1$. So $ (a^2 + b^2, AB) = 1$.5. Proof: If $a, b\in\mathbf{n^*}$, then sequence: $a $, $2a$, $\cdots$, $ba $ The number of items that can be divisible by $b $ equals $ (A, b) $.Answer:Make $ (A, B) = d$, $a = da_1$, $b = db_1$, $ (a_1, b_1) = 1$. The original number is listed as $ $da _1, da_2, \cdots, db_1da_1,$$ at the same time divided by $b $ $$\frac{a_1}{b_1}, \frac

1. Maximum MappingThere are n strings, each of which is composed of the uppercase characters of A-j. Now you map each character to a 0-9 number, with different characters mapped to different numbers. Each string can then be treated as an integer, and the only requirement is that the integers must be positive integers and their strings cannot have leading zeros. Now how do you map characters to make the sum of the integers represented by these strings the largest?Input Description:Each set of tes

A string that contains only ' a ', ' B ', and ' C ', if there is one in a contiguous string of length 3 that is exactly ' a ', ' B ', and ' C ', then the string is pure, otherwise the string is Diablo. For example:BAACAACCBAAA continuous substring "CBA" contains ' a ', ' B ', ' C ' each one, so is the pure stringAabbccaabb does not exist a continuous substring of length 3 contains ' a ', ' B ', ' C ', so it is a dark stringYour task is to calculate a string of length n (containing only ' A ', '

\cdot k$, where $p _1$ is prime and $p 5. Find the $x $, $y $, $z $ for all primes that satisfy the equation $x ^y + 1 = z$.Answer:$x ^y$ differs from $z $ parity, so $x = 2$. $$\rightarrow 2^y + 1 = z$$ If $y $ is odd, then $z $ is composite, so $y = 2$, $z = 5$.6. Proof: $n > 2$, there must be a prime number between $n $ and $n!$.Answer:Easy to know $ (n!, n!-1) = 1$. The primes in $1\sim n$ can be evenly divisible $n!$ but not divisible $n! -1$, so $n! -1$ must contain a prime number that is

Question Surface First, consider what is the optimal strategy. In fact, this optimal strategy is one by one from big to small. Because a small one won't and won't affect the big one, it is obviously the best and necessary, so let's enumerate the factor and store it in vector, then we can directly simulate it to get $ 50pts $ (as if I had made water from Grandpa bi's data (?) Resulting in 80 PTS (FOG) Consider the random press process before reaching $ K $ and set $ exp [I] $ (do not write this i

Question Portal This question looks dizzy at the beginning...\ (Qwq \). First, we need to clarify the altitude Temperature in the question. The temperature is affected by the altitude. Each time we change the altitude, we need the temperature. When we start reading data, we can process the start point.\ (N \)The temperature of the location and the elevation difference of each location. Each read operation affects a certain interval, and the relative altitude in the interval remains unchanged,
