How many sequences of n ones and n negative ones are there such that adding term by term from left to right gives a nonnegative sum at each step? A part of your answer, list all possible such sequences for n = 1 and n = 2, and describe (in different words) the condition the sequence must satisfy at any point along the sequence.
