摘要：这是一大数题,直接套模板,其实跟十进制差不多,不过把对10取余改成对26取余就行了,水过#include<stdio.h>#include<string.h>#define max 250int num[max];char str1[max],str2[max];void cal( ){ memset( num,0,sizeof( num ) ); int len1 = strlen( str1 ),len2 = strlen( str2 ); for( int i = 0; i < ( len1 > len2 ? len1 : len2 ); ++i )/ 阅读全文

摘要：这是大数相乘的一模板题;先把两个字符串变成ASCII码(不能和倒置放在一块,否则会出错),然后把他们全部倒置,然后再将他们相乘,最后再进位,不过这样会超时,将会在近段时间内发布不超时的代码#include<stdio.h>#include<string.h>#include<stdlib.h>#define Max 100000int num[Max];char str1[Max] = {0},str2[Max] = {0};void cal( ){ int len1 = strlen( str1 ),len2 = strlen( str2 ); for( 阅读全文
