In combinatorics, stars and bars (also called "sticks and stones", [1] "balls and bars", [2] and "dots and dividers" [3]) is a graphical aid for deriving certain combinatorial theorems. It can be used to solve many simple counting problems , such as how many ways there are to put n indistinguishable balls into k distinguishable bins. [ 4 ]
Alternatively, we can first give candies to the oldest child so that we are essentially giving candies to kids and again, with stars and bars and double counting, we have ( n + k − 1 k − 1 ) = ∑ i = 0 n ( n + k − 2 − i k − 2 ) , {\displaystyle {\binom {n+k-1}{k-1}}=\sum _{i=0}^{n}{\binom {n+k-2-i}{k-2}},}
