What will be the return value of someCoolFunction("[ab][bc][ca]", "[", "]")? public static String[] someCoolFunction(String str, String open, String close) { if (str == null || open == null || close == null) { return null; } int strLen = str.length(); if (strLen == 0) { return null; } int closeLen = close.length(); int openLen = open.length(); List list = new ArrayList(); int pos = 0; while (pos < (strLen - closeLen)) { int start = str.indexOf(open, pos); if (start < 0) { break; } start += openLen; int end = str.indexOf(close, start); if (end < 0) { break; } list.add(str.substring(start+1, end)); pos = end + closeLen; } if (list.isEmpty()) { return null; } return (String[]) list.toArray(new String [list.size()]); } ["bb", "cc", "da"] ["a", "b", "c"] ["ab", "bc", "ca"] ["b", "c", "a"] ["c", "b", "a"] Question 4 A perfect number is a positive integer that is equal to the sum of its proper positive divisors (factors) excluding the number itself. Complete the following function which determines whether a given number is perfect or not. int perfect(int n) { int tot = 1; int i; // ********************* // What's the code here? // ********************* return tot == n; } for (i = 2; i < n; i++) { if ( (i % n) != 0 ) { tot += i; } } for (i = 2; i < n; i++) { if ( (i % n) == 0 ) { tot += i; } } for (i = 2; i < n; i++) { if ( (n % i) == 0 ) { tot += i; } } for (i = 2; i < n; i++) { if ( (n % i) != 0 ) { tot += i; } }
