| Hardwood Species | |
| Hardwoods are the botanical group of trees that have broad leaves, | |
| produce a fruit or nut, and generally go dormant in the winter. | |
| America’s temperate climates produce forests with hundreds of | |
| hardwood species —trees that share certain biological characteristics. | |
| Although oak, maple and cherry all are types of hardwood trees, for | |
| example, they are different species. Together, all the hardwood species | |
| represent 40 percent of the trees in the United States. | |
| On the other hand, softwoods, or conifers, from the Latin word | |
| meaning “cone-bearing”, have needles. Widely available US softwoods | |
| include cedar, fir, hemlock, pine, redwood, spruce and cypress. In a | |
| home, the softwoods are used primarily as structural lumber such as | |
| 2×4s and 2×6s, with some limited decorative applications. | |
| Using satellite imaging technology, the Department of Natural Resources has compiled an inventory | |
| of every tree standing on a particular day. You are to compute the total fraction of the tree population | |
| represented by each species. | |
| Input | |
| The first line is the number of test cases, followed by a blank line. | |
| Each test case of your program consists of a list of the species of every tree observed by the satellite; | |
| one tree per line. No species name exceeds 30 characters. There are no more than 10,000 species and | |
| no more than 1,000,000 trees. | |
| There is a blank line between each consecutive test cases. | |
| Output | |
| For each test case print the name of each species represented in the population, in alphabetical order, | |
| followed by the percentage of the population it represents, to 4 decimal places. | |
| Print a blank line between 2 consecutive test cases. | |
