Problem Restatement We are given equations representing division relationships between variables. For example: a / b = 2.0 b / c = 3.0 We are also given queries like: a / c c / a a / e We need to compute the value of each query. If the query cannot be determined from the equations, return: -1.0 The equations are guaranteed to be valid, and there is no contradiction....
