Team Uniforms - Algorithm

Here's your approach with polymorphism:

$1.$ Define a base

Team class with virtual getHomeColor() and getAwayColor() methods.

$2.$ Define a

StandardTeam derived class that stores and returns the colors.

$3.$ Read $n$ teams into an array of Team pointers.

$4.$ Initialize count to zero.

$5.$ For each pair $(i, j)$ where $i \neq j$: if teams[i]->getHomeColor() equals teams[j]->getAwayColor(), increment count.

$6.$ Output count. The polymorphic calls let you extend to new team types smoothly.
