Find rule! N! The last Non-zero-digit value. For example, 2 is the last value of 120 instead of 0.The input N is larger than the limit value and must be saved in large numbers.Note that the number of the last 0 is equal to the number of five factors. Set F (n) to n! .Then f (n) = (N % 5 )! * F (N/5) * 2 ^ (N/5) % 10The number of factor 2 is always greater than 5. Each of the five consecutive groups is divided into one group starting from 1. The multip

Hdu oj 1061 Rightmost Digit (fast power algorithm), hdurightmost Here we will first explain the quick power algorithm: Fast modulo Algorithm I have not found a detailed description and explanation of the quick power algorithm on the website. Here, I provide a complete explanation of the quick power algorithm, using the C language, readers of different languages have to change their positions. After all, many people read C ~ The so-called rapid power

Label: Print 1 to the maximum n digits Description: Enter the number N and print the n-digit decimal number from 1 to the maximum in order. For example, if you enter 3, the number of three digits from 1, 2, and 3 to the maximum is 999. Analysis description: The first thought is to first calculate the maximum N-digit number, and then print it from 1 to the maximum N-

A friend encountered a problem during the interview, write programs in Java, calculate two 20-digit multiplication. Listen, it's funny, just try to make it.The idea is to use code to simulate the process of multiplying the hand, that is, the multiplication of a bit, the result remains on the corresponding bit, and the rounding problem is solved.Ask if the other side is solved, the other side told me that Java has a Java.math.BigInteger package, there

In html, color represents the most commonly used 6-digit hexadecimal code notation. In addition, color can also be represented by rgb (r, g, B). r, g, B Represents red, green, and blue in decimal number or percentage from 0 to, respectively. If you are interested, you can see that there are 3 Representation Methods in the HTML, the most commonly used is the 6-digit hexadecimal code notation. For example, bg

PHP introduces two functions that implement the digit zero filling function. In PHP, there are at least two functions that can help us quickly implement zero-padding: The first is the PHPstr_pad function: Copy the code as follows: # str_pad-use another string to fill in characters. there are at least two functions in PHP that can help us quickly implement zero padding: The first is the PHP str_pad function: The code is as follows: # Str_pad-use anot
