::::
:::
**Propriétés:**
1. les feuilles sont toutes sur l'avant dernier ou dernier niveau.
2. les feuilles de profondeur maximale sont "tassée" à gauche.
# Le tas (ou heap)
## Définition
* Un arbre est un tas, si la valeur de chacun de ses descendants est inférieure
ou égale à sa propre valeur.
## Exemples (ou pas)
```
16 8 14 6 2 10 12 4 5 # Tas
16 14 8 6 2 10 12 4 5 # Non-tas, 10 > 8 et 12 > 8
```
## Exercices (ou pas)
```
19 18 12 12 17 1 13 4 5 # Tas ou pas tas?
19 18 16 12 17 1 12 4 5 # Tas ou pas tas?
```
. . .
```
19 18 12 12 17 1 13 4 5 # Pas tas! 13 > 12
19 18 16 12 17 1 12 4 5 # Tas!
