Solution: Frog Jump
Explore how dynamic programming helps solve the Frog Jump problem by tracking valid jump lengths to reach each stone. Learn to implement a C++ solution that efficiently checks all possible jumps to determine if the frog can cross the river safely. This lesson guides you through the algorithm, data structures, and complexity analysis for solving this optimization challenge.
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
If the frog’s last jump was of length
