Question
Question omitted.
Analysis: I expanded the formula, pushed something out, enumerated digits, and then obtained an X, if X represents the number under the base where the current total number of digits minus one, the current number of
Obtain the highest bitwise by multiplication.
# Include # include # include using namespace STD; // # define test int main () { # ifdef test freopen ("input.txt", "r ", stdin); # endif int base, n, m; while (CIN> base> N> m) { If (M = 1)
This question can be pushed forward to the number of all BITs by the known last bits of the first multiplier.
For example:
The given base number is 10, the last digit of the first multiplier is 7, and the second multiplier is 4.
List the following
