How to print "No solution".

printf("No solution\n");

or

printf("Case %d: No solution\n",id);
printf("Case %d:No solution\n",id);

Suppose S is a string S[1....n], we call a substring P of S weak repeated,if
P=s[i...j] satisfied : there exists another subtring T=s[k...l], T equals to P, and i != k.
can someone give me an answer

wa...

Thank you ,sir ,I got accept when I change the com() function: ///////////////////////////////////////////////////////////// #include<cstdio> #include<iostream> #include<cstring> #include<algorithm> using namespace std; #define N 150 int n; char a[N][N]; int b[N]; bool com(int x, int y){ return strc...

//when I use STL sort in my code ,I always get RunTime error, but when I write a sort myself , i immediate get AC. Could anybody give me an answer?? it is in the solve function below. #include<cstdio> #include<iostream> #include<cstring> #include<algorithm> using namespace std; #define N 150 int n; ...

Problem 10290 && problem 10400, the time limitation will exceed 3s ,so the server should adjust them. 3X.

the problem said the time limit is 100s, but why i got a TLE in 3s.
and a old AC code, i resubmit to the new judge and get a TLE .

very slow....
some suggestion: first ,the problems list i have solved.
second, the problems list i have tried but not solved.
all the above is displayed in the old judge ,but the new judge do not have .

I submit a code which got AC before, and now get a TLE...
I am sure that there are some mistake in the judge.

solved.thank you.when i didnot include the <string> library,the compiler didnot give any warning...,so i submit a wrong code.

another code got AC over 3000ms... I got TLE in 3000ms.

it states in the problem ,that the running time will be 100seconds,but why i run only 3seconds ,and get a TLE??
