Implement a function distinct(...), which expects an array of integers and sorts these ascendingly. The array shall not contain repetitions of any integer value but '1'. Repetitions of '1' should be the last values of the array.

distinct.php

<?php

/**
 * @param array $array
 *
 * @return array | false
 */
function distinct( array $arr ) {

	if ( is_array( $arr ) ) {

		// checking if we have value "1" in array and how many :
		$_tmp_array = array_count_values( $arr );
		$count_val_in_array = isset($_tmp_array[1]) ? $_tmp_array[1] : false;

		$arr = array_unique( $arr );
		sort( $arr );
		
		// If we have "1" in array, merge values to end of array :
		if($count_val_in_array) {
		    for($i = 0 ; $i < $count_val_in_array - 1; $i++) {
		        array_push($arr, 1);
		    }
		}

		return $arr;

	} else {
		return false;
	}


}

$test = array( 1, 21, 3, 44, 5, 1, 1, 1, 23, 4, 5, 5 );

print_r( distinct( $test ) );
