Turcane

#4410

Pe un câmp asemănător cu o tablă de şah cu M linii şi N coloane, o ţurcană se află în pătrăţelul de coordonate (1,1) aflat în colţul din stânga-sus al tablei şi vrea să ajungă în pătrăţelul de coordonate (M,N) aflat în colţul din dreapta-jos al tablei. Ea poate efectua sărituri de lungime cel mult P la dreapta, de lungime cel mult Q în jos, de lungime cel mult R pe diagonală spre dreapta-jos, precum şi săritura calului, adică două pătrăţele la dreapta şi unul în jos sau două în jos şi unul la dreapta. Orice săritură trebuie să schimbe poziţia ţurcanei. Se dă un număr întreg C.
- Dacă C=1, să se determine numărul minim de sărituri necesare pentru a ajunge în pătrăţelul de coordonate (M,N).
- Dacă C=2, să se determine numărul de moduri în care poate să ajungă în pătrăţelul de coordonate (M,N), nu neapărat cu număr minim de sărituri.
