Suppose that I have an array

```julia
X = ["a","b","c","d"]

```

with the corresponding weights

```julia
weight = [1,4,3,2]

```

How can I make heaps of X using weight

```julia
using DataStructures
weight_heaps =BinaryMaxHeap(weight)
# What I want to do
X_heaps = BinaryMaxHeap(X,weight=weight)

```

I can not find it in the DataStructures package documentation. Thank you so much.

So you want a heap with associated data? Perhaps you’re looking for a priority queue:
