Question: implement the function Double Power (double base, int exponent) to calculate the power of base's exponent. Overflow is not required.
Analysis: this seems simple. Some
The fast power algorithm can be said to be a kind of ACM competition is necessary, and is also a very basic type of algorithm, given that I have been learning more fragmented, so today with this post summed upFast multiplication usually has two
I. Problem description:
Calculate (a ^ power) % m, where power is a non-negative big integer, A, M is an integer greater than 1.
Ii. Problem Analysis:
Obviously, power is a big integer, so the overflow of Power computing must be considered. How can
Determines whether an integer is the power of another integer.
I recently learned about the 20 most popular questions about c # on the Internet in Microsoft's virtual course. I want to write down my personal understanding and solutions for this
Quickly determine whether a number is a power of 2, if so, and determine how many times the square!when the power of 2 is written in binary form, it is easy to find a feature: The binary is only a 1, and 1 followed by n 0, so the problem can be
Give a one-line CExpression to test whetherUnsigned int is a power of two.
Check whether an unsigned integer is a power of 2 using a single line of C expression (the power of 2 refers to the power of a positive integer of 2, such as, 16)
Answer:
(
