+## points particuliers :
+
+- les fonctions d'actions (puches, swapes, rotates) recoivent une ou les deux piles a et b, et la liste chainee *solution* qui doit accueillir les noms des actions successives
+- mais pour pouvoir imprimer l'état des deux piles a et b a chaque etape il faudrait que chaques fonctions recoivent les deux piles, ce qui n'est pas le cas : sa() par exemple ne recoit pas la pile b
+- donc j'ai stocké les deux piles dans les deux premiers maillons de la chaine solution, car toutes les fonctions d'actions la recoivent

 ## ce programme push_swap.c s'organise de la facon suivante :
 
 1. des fonctions pour faire fonctionner l'algorithme de tris (principalement parsing des donnees, et les actions utilisees par l'algorithme de tris : push, swap, rotate et reverse rotate) :
