Solution: Water and Jug Problem

Explore how to solve the Water and Jug problem by understanding the math behind it, including the use of the greatest common divisor. This lesson teaches you to efficiently determine if a target volume can be measured using two jugs with given capacities. Learn to apply Bézout's Identity and optimize your solution's time and space complexity.

Statement

You are given two jugs with capacities of x liters and y liters, respectively, along with an infinite water supply. Determine whether it is possible for the total amount of water in both jugs may reach target liters.

You may perform the following operations any number of times:

  • Fill either jug completely with water.

  • Empty either jug completely.

  • Pour water from one jug into the other until either the receiving jug becomes ...
