My answer:
<?php $array = array_map('intval', explode(' ', readline())); $count = count($array); $bestCount = 0; $bestElement = 0; for ($i = 0; $i < $count; $i++) { $repeat = 1; for ($j = $i + 1; $j < $count; $j++) { if ($array[$i] == $array[$j]) { $repeat++; } else { break; } } if ($repeat > $bestCount) { $bestCount = $repeat; $bestElement = $array[$i]; } } for ($i = 0; $i < $bestCount; $i++) { echo $bestElement . ' '; }

To show the result (the last - 23rd line) you can also use str_repeat function in PHP:
str_repeat ( string $input , int $multiplier ) : string
Returns input repeated multiplier times.
input
The string to be repeated.
multiplier
Number of time the input string should be repeated
My code:
<?php $array = array_map('intval', explode(' ', readline())); $count = count($array); $bestCount = 0; $bestElement = 0; for ($i = 0; $i < $count; $i++) { $repeat = 1; for ($j = $i + 1; $j < $count; $j++) { if ($array[$i] == $array[$j]) { $repeat++; } else { break; } } if ($repeat > $bestCount) { $bestCount = $repeat; $bestElement = $array[$i]; } } echo str_repeat("$bestElement ", $bestCount);
