77. Let a non-decreasing sequence of real numbers a1 ≤ a2 ≤ ... ≤ аn and real numbers b1 ≤ b2 ≤ ... ≤ bm be given. It is required to indicate the places where the elements of the sequence b1, b2, ..., bm should be inserted into the first sequence so that the new sequence remains increasing. Kitchen RULES
