A. Comparing Two Long Integers

果然还是我太天真了（长整数比较不就是long long么........于是一直wa on 9，直到今天起床看了看别人的代码才恍然大悟。。。

#include<stdio.h>#include<string.h>const int MAX_N = 1000005;int main(){char a[MAX_N],b[MAX_N];int lena,lenb,la,lb,pa=0,pb=0,i;scanf("%s%s",a,b);lena=strlen(a);lenb=strlen(b);while(pa<lena&&a[pa]=='0') pa++;while(pb<lenb&&b[pb]=='0') pb++;la=lena-pa;lb=lenb-pb;if(la>lb)printf(">\n");else if(la<lb)printf("<\n");else{for(i=pa;i<lena;i++){if(a[i]>b[i-pa+pb]){printf(">\n");return 0;}else if(a[i]<b[i-pa+pb]){printf("<\n");return 0;}}printf("=\n");}return 0;}
