Soit ABC un triangle rectangle en A. Écrire un algorithme capable de calculer la longueur du segment bleu :

Votre algorithme doit afficher les mêmes résultats pour les exemples suivants :

pour segment n°1 = 21, segment n°2 = 29 on affiche 20.
pour segment n°1 = 25, segment n°2 = 20 on affiche 15.
