After getting a lot of WA finally i solved... :D
Some instructions to new solver:
1. consider graph as bidirectional
2. need not to visit those vertices's which have no edge. u can ignore those. Exception if r != 0 !!
3. must have to visit all edges (Eulerian cycle)

consider these test cases ...

for prob 10209
3rd eqn: 2x+y+z=(pi/3 - sqrt(3)/4)a^2
2x+y+z
= ((1/2) * s * a) - ((1/2) * c * (a/2))
= yellow shade of circle
= ((1/2) * a * (2/3) * pi * a) - (.5 * sqrt(3)*r * (r/2))
= ((1/3) * pi * a^2) - (sqrt(3)/4 r^2)
= ((1/3) * pi - sqrt(3)/4) * a^2

will any one please tell me why it is giving P.E?


#include<stdio.h>

int strlen(char str[])
{
int i;
for(i=0;str[i]!=NULL;i++);
return i;
}

void main()
{
int i=0,n,k,j,mxm=0;
char str1[200][200],str2[200][200];

while(gets(str1[i]))
{
k=strlen(str1[i]);
if(k>mxm)
mxm=k;
i++;

}

for ...

can any one tell me what is the problem with my code? why it is showing output limit exceed? :evil:
