print repeated character in string javascript code example
Example 1: typescript algorithm to find repeating number sequences over time
String arr[] = {"12341234abc", "1234foo1234", "12121212", "111111111", "1a1212b123123c12341234d1234512345"};
String regex = "(\\d+?)\\1";
Pattern p = Pattern.compile(regex);
for (String elem : arr) {
boolean noMatchFound = true;
Matcher matcher = p.matcher(elem);
while (matcher.find()) {
noMatchFound = false;
System.out.println(elem + " got repeated: " + matcher.group(1));
}
if (noMatchFound) {
System.out.println(elem + " has no repeation");
}
}
Example 2: js string times
