Why i got WA? #include <iostream> using namespace std; #include <cstring> #include <cstdio> #define N 10000 typedef struct { char c; long num; }Z; int main(int argc, char* argv[]) { char str[N]; long i,j,k,l,sum; Z z; z.num=0; while(gets(str)) { l=strlen(str);sum=0; for(i=0;i<l;i++) { if(str >='0'&&...

i don't know why i got Presentation Error it's my code #include <iostream> using namespace std; #include <cstring> #include <cstdio> int main(int argc, char* argv[]) { char str[1000]; char copy[1000]; char s[1000][1000]; long i,j,l,m,k; bool flag,flag2; while(gets(str)) { l=strlen(str); j=0; copy[l]...

382 WA pls give me some test cases

i don't know why i got WA instead of AC. my code following: #include <iostream> using namespace std; #include <cstring> #include <cstdio> #include <cmath> int main(int argc, char* argv[]) { char str[1000]; long copy[110]; long s[110]; long i,j,k,l,sum,val,i_save,j_copy; //bool flag; for(i=0;i<100;i+...

about next_permutation() my VC6.0 can't run this function
why?

my code :( #include "iostream.h" #include "stdio.h" #include "string.h" int main(int argc, char* argv[]) { long N; char h1[3],h2[3]; char b1[15],b2[15]; long val; long l1,r1; long i,j; long sum1,sum2; long sum; char c; while(cin>>N) { for(i=0;i<N;i++) { cin>>h1>>c>>h2; l1=strlen(h1); r1=strlen(h2); ...

I don't know why i always got Time Limit Exceeded. My code: #include "iostream.h" #include "stdio.h" #include "math.h" #include "string.h" int main(int argc, char* argv[]) { long a,b,i,j,k,num,l; double t; double sum; while(cin>>a>>b) { num=0; l=b-a+1; for(i=a;i<=b;i++) { j=i*i+i+41; t=sqrt(j); for(...

why? anyone could help me my code: #include "iostream.h" #include "stdio.h" #include "math.h" #include "string.h" int main(int argc, char* argv[]) { char str[2000]; char m[100]; long b; long i,j,l1,l2; long sum_p,sum_m; long val; long sum; while(cin>>b) { sum_p=0; sum_m=0; if(b==0) break; else if(b=...

You are calling strlen each time in the for loop you print the input number. And in fact, you can print out a char array directly just like C++ strings. Just do a cout << str for the places where you print the input number character by character and the TLE should go away. If not, you might wan to ...

I got Time Limit Exceeded,but i don't know why my code: #include "iostream.h" #include "stdio.h" #include "string.h" #include "math.h" int main(int argc, char* argv[]) { char str[1010]; int s_odd,s_even; int s; int i,j; while(cin>>str) { if(strcmp(str,"0")==0) break; else if(str[0]=='-') break; else...

i found the run time is too long. this is my code: #include "iostream.h" #include "stdio.h" int main(int argc, char* argv[]) { long n; long sum; long i; while(cin>>n) { sum=1; for(i=n;i>0;i--) { sum*=i; } while(sum>0) { if(sum%10!=0) { cout<<sum%10<<endl; sum/=10; break; } else sum/=10; } } return 0...
