Maximal Sequence

/* Write a JavaScript function findMaxSequence(arr) that finds the maximal sequence of equal elements in
an array and returns the result as an array. If there is more than one sequence with the same maximal length,
print the rightmost one. Write JS program sequenceFinder.js that invokes your function with the sample
input data below and prints the output at the console. */
