Arduino Code Snippet: Serial.println(comp(su,um)) and int time=1

This code snippet appears to be incomplete and does not provide enough context to determine its purpose or functionality. Please provide more information or surrounding code for a better understanding. It includes the use of 'Serial.println' to print the result of the 'comp' function, which takes two arguments 'su' and 'um'. Additionally, it declares an integer variable 'time' with a value of 1.
