Can anyone hel me? I got WA 20. I used linear Diophantine equation and extended Euclidian algorithms from cp-algorithms.com, but I got WA. These are links that I used:

My code is :

#include #define PII pair #define db(x) cerr<<#x<<"="<

using namespace std;

ll gcd(ll a,ll b,ll &x,ll &y) { if(a==0) { x=0; y=1; return b; } ll x1,y1; ll d=gcd(b%a,a,x1,y1); x=y1-(b/a)*x1; y=x1; return d; }

bool find_any_solution(ll a,ll b,ll c,ll &x0,ll &y0,ll &g) { g=gcd(abs(a),abs(b),x0,y0); if(c%g) return false; x0*=c/g; y0*=c/g; if(a<0) x0=-x0; if(b<0) y0=-y0; return true; }

void shift_solution(ll &x,ll &y,ll a,ll b,ll cnt) { x+=cntb; y-=cnta; }

PII find_all_solution(ll a,ll b,ll c,ll minx,ll maxx,ll miny,ll maxy) { ll x,y,g; PII res= {-1,-1}; if(!find_any_solution(a,b,c,x,y,g)) return res; a/=g; b/=g;

}
