# In next commented section there is a bug when trying to validate if a leaf exists in the "features" dict. Essentially, a "leaf" has
# the form: (feature_1, feature_2, ..., feature_n) and the "keys" and "values" of the "features" dict has the form:
# key = feature
# value = frequency
# So, the condition must be changed in order to evaluate the case when a "feature" from the current "leaf" exists in the "features" dict
# Otherwise, for some specific cases this loop crashes
# ------ Original loop ---------- #
# for leaf in leaves.keys():
# if not leaf in features:
# for e in leaf:
# features[abs(e)] = 1
# else:
# features[abs(e)] += 1

# ------ Fixed loop ---------- #
for leaf in leaves.keys():
if not leaf in features:
for e in leaf:
for e in leaf:
if abs(e) not in features.keys():
features[abs(e)] = 1
else:
features[abs(e)] += 1
