Leetcode 1883. Minimum Skips to Arrive at Meeting On Time

Given road lengths and a speed where after each road you must wait until the next integer hour (unless you skip the wait), find the minimum number of skips needed so total travel time ≤ hoursBefore, or return -1 if impossible. The core challenge is handling the cumulative fractional times and ceil-induced waits — typically solved by dynamic programming that tracks the best elapsed time achievable for each number of skips.
