| telegrapher(L,C,R=0,G=0,n=100) | |
| returns an array of differential equations that can be | |
| used to solve for the travelling voltages and currents as a function of time. | |
| All quantities are expected to be per-length quantities (in S.I. units). | |
| The problem is solved by discretizing the transmission line into n sections. If | |
| the solution is too coarse then try changing n. |

| // You are a professional robber planning to rob houses along a street. Each house has a certain amount of money stashed, the only constraint stopping you from robbing each of them is that adjacent houses have security system connected and it will automatically contact the police if two adjacent houses were broken into on the same night. | |
| // Given a list of non-negative integers representing the amount of money of each house, determine the maximum amount of money you can rob tonight without alerting the police. | |
