I was given a task. Write an algorithm so that, the input of 2 lists of data, will have at least one in common.
So, this is my algorithm: (I write the code in php)
$arrayA = array('5', '6', '1', '2', '7');
$arrayB = array('9', '2', '1', '8', '3');
$arrayC = array();
foreach($arrayA as $val){
if(in_array($val, $arrayB)){
array_push($arrayC, $val);
}
}
Thats my own algo, not sure if its a good one. So, based on my algorithm, how to find the formula of best case and worst case (big O)?
Note: Please do let me know, if my algorithm is wrong. My goal is " input of 2 lists of data, will have at least one in common."
