// input comes from STDIN (standard input)
// You can this code :$stdin = fopen(“php://stdin”, “r”);

 $line = strtolower(trim($line));
 // split the line into words while removing any empty string

 // increase counters
 foreach ($words as $word) {
 $word2count[$word] += 1;

// write the results to STDOUT (standard output)
// what we output here will be the input for the
