WitrynaThe power function is used to find the power of any given number. The power function is a predefined library function of the math.h header file, and we need to import the math.h header file in our program while using the pow () function. In other words, a pow () function is used to calculate the power of the base number (x) by raising the … WitrynaImplement pow (x, n), which calculates x raised to the power n (i.e., x n ). Example 1: Input: x = 2.00000, n = 10 Output: 1024.00000 Example 2: Input: x = 2.10000, n = 3 …

When n is odd, the formula is a little more complex: subtract 1 from n, make a recursive call for n/2, square the result, and multiply by x. Witryna23 gru 2024 · Recursively call power pass x and n/2 and store its result in a variable sq. Check if dividing n by 2 leaves a remainder 0; if so then return the results obtained from cmul(sq, sq) Check if dividing n by 2 does not leaves a remainder 0; if so then return the results obtained from cmul(x, cmul(sq, sq)). immortal emperor luo wuji chapter 2
