Usage

Initialisation

from sumtree import SumTree
st = SumTree(1024)
st.add(10)
print(st.total)     # 10
print(len(st))      # 1
print(st.capacity)  # 1024

Sampling data

from sumtree import SumTree
st = SumTree(1024)
for i in range(1024):
    st.add(i)
index, value = st.get(500)
print(index, value)  # 32, 32.0
