Solution: Frog Jump
Explore the dynamic programming approach to solve the frog jump problem where a frog attempts to cross a river by jumping on stones at certain positions. Understand how to track possible jump lengths and use a mapping technique for efficient lookups. This lesson helps you implement a solution that determines if the frog can successfully reach the last stone using optimal time and space complexity techniques.
We'll cover the following...
Statement
A frog is trying to cross a river by jumping on stones placed at various positions along the river. The river is divided into units, and some units contain stones while others do not. The frog can only land on a stone, but it must not jump into the water.
You are given an array, stones, that represents the positions of the stones in ascending order (in units). The frog starts on the first stone, and its first jump must be exactly
