XXXXXXX +Everyone will starve if you only plant such a small number of seeds. Re-reading the almanac, it looks like the `seeds`: line actually describes **ranges of seed numbers**. + +The values on the initial `seeds:` line come in pairs. Within each pair, the first value is the **start** of the range and the second value is the **length** of the range. So, in the first line of the example above: +``` +seeds: 79 14 55 13 +``` +This line describes two ranges of seed numbers to be planted in the garden. The first range starts with seed number `79` and contains `14` values: `79`, `80`, ..., `91`, `92`. The second range starts with seed number `55` and contains `13` values: `55`, `56`, ..., `66`, `67`. + +Now, rather than considering four seed numbers, you need to consider a total of **27** seed numbers. + +In the above example, the lowest location number can be obtained from seed number `82`, which corresponds to soil `84`, fertilizer `84`, water `84`, light `77`, temperature `45`, humidity `46`, and **location `46`**. So, the lowest location number is `46`. + +Consider all of the initial seed numbers listed in the ranges on the first line of the almanac. + +
