+
+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. What is the lowest location number that corresponds to any of
+the initial seed numbers?
