Binomial theorem One can define\[{r \choose k}=\frac{r\,(r-1) \cdots (r-k+1)}{k!} =\frac{(r)_k}{k!}\] Then, if \(x\) and \(y\) are real numbers with \(|x| > |y|\)( This is to guarantee convergence. Depending on \(r\), the series may also converge som…
There are N gas stations along a circular route, where the amount of gas at station i is gas[i]. You have a car with an unlimited gas tank and it costs cost[i] of gas to travel from station i to its next station (i+1). You begin the journey with an e…
