input: Write a python function to predict customer purchase using RandomForestClassifier.
  assert predict_customer_purchase([[1, 0, 0, 0, 1], [0, 1, 0, 0, 0], [0, 0, 1, 0, 1]]) == [1, 2, 3]
  assert predict_customer_purchase([[0, 0, 0, 1, 1], [1, 1, 0, 0, 1]]) == [2, 1]
output: def predict_customer_purchase(features):
