i m power

1:The problem is as follows:What is the value of a^n% m? n is an integer from 1 to 10^18.To find the N-square of a number, the naïve algorithm is the complexity of the direct for Loop, O (N).But for this problem N is really too big, O (n) will also time out, then need a faster algorithm, fast power algorithm.Ask A^n, if know a^ (N/2) The second party words, then a square on it.Then according to this idea can use the idea of divided treatment.The code

Topic link http://acm.hdu.edu.cn/showproblem.php?pid=4549;It is easy to understand the topic of Chinese. But at first I read the wrong question, this problem haha. At first I read the wrong question, used a quick power to solve, needless to say, WA, see the passage rate of the topic is not high, I think there will be what pit ah. But I'm the big pit, haha.Do not say, directly to say the question, first discuss k=1,2,3; This should be solved, not much

When the MoD is a large number p, there are times when multiplication may explode long, using fast multiply or fast power. Reference: http://www.cnblogs.com/whywhy/p/5066730.html First on the template: Quick multiply: ll multi (ll a,ll b,ll m) { ll ans=0; while (b) { if(b1) (ans+=a)%= m; (A=a*2)%= m; b/=2; } return ans;} Fast power: ll Pow_mod (ll a,ll

Create a power plan what to choose To create a power plan is a timing function, such as how long we do not use the computer automatically into the screen saver or longer without the system automatically sleep state. How do I create a power plan? (Win8.1) 1. Click the "Start" option, as shown below.2. Select the "Control Panel" option to open the entry details

New Wi-Fi standard HaLow announcement: Bluetooth with low power consumption and high power consumption Recently, the Wi-Fi Alliance has passed a new standard, namely the expansion of the 802.11ah standard, which is called "HaLow ". As named by myself, HaLow focuses on low-power and low-power devices. The operator h

Recently writtenProgramWe need to solve the feature values and feature vectors of the matrix. We thought this was not a very complicated problem. The problem scale is large (the matrix size is about 15000*15000, or even larger) in addition, the computation should be as fast as possible and become abnormal and complex. Of course it is quite easy to use MATLAB, but it requires the use of C or C ++ programs ...... I have tried several different methods and have made myself confused. Here I will s

PS: Reprint, write their own less than others, afraid of misleading. Reprint Address: http://www.cnblogs.com/CXCXCXC/p/4641812.htmlFirst of all, the purpose of the fast power is to do a quick exponentiation, assuming we ask a^b, according to the naïve algorithm is to connect A to B, so that the time complexity is O (b) is also the O (n) level, fast power to do O (Logn), a lot faster. It has the following pr

The handheld device enters the low-power mode to reduce the operating current and provide the standby time. If some devices are turned on and not disabled, this may cause a waste of energy. Factors that affect power consumption include clock, GPIO, and power supply. If the clock is caused, you can check the Clock Tree of the system to see which clocks are turned

After the power of 2 is written in binary form, it is easy to find that there is only one 1 in binary, and 1 followed by n 0; therefore, the problem can be converted to determining whether n zeros are followed by 1. If we subtract this number from 1, we will find that the only one will change to 0, and the original n 0 will change to 1; therefore, the original number and the number after the first subtraction will be zero after calculation. The faste

Several power function calculation methods and Power Function MethodsIntroduction We know that the Base e of the natural logarithm is defined as the following limit value: This formula is suitable for some tests on power function calculation. The result is an approximate value of e, so you don't have to worry that the calculation result will overflow when n is l

Fast PowerAs the name implies, it is a fast calculation of the number of times the power. Its time complexity is O (log?) n), the efficiency is greatly improved compared with the simple O (n).Principle of fast power realizationThe principle of fast power comparison understood, that is, if we ask for 3^11 , in fact, the more common way is For 1:11a*=3;
