WebDec 2, 2024 · find its power and check it for super power. Below is the implementation of the above approach: C++ Java Python3 C# PHP Javascript #include #define MAX 100000 using namespace std; bool prime [100002]; void SieveOfEratosthenes () { memset(prime, true, sizeof(prime)); for (int p = 2; p * p <= MAX; p++) if (prime [p] == true) WebDec 18, 2024 · The power function has two base cases: n = 0 and n = 1. The power function has two recursive calls. Only one of them is made in any given call. Let's first consider the case when n is even: In that case, the recursive call is made with n / 2. If all calls would use this case, then you half n in each call down until you reach 1. huffington post readership

WebNov 19, 2010 · Firstly calculate t1 = totient (m), after t2 = totient (t1) and so on. For example take x=b^ (c^d). If t1=totient (m), a^x mod m = a^ (b^ (c^d) mod t1), and we are able to say b^ (c^d) mod t1 = b^ (c^d mod t2) mod t1, where t2 = totient (t1). everything we are calculating using exponentiation by squaring algorithm. WebIn C++ the "^" operator is a bitwise XOR. It does not work for raising to a power.
