Here, we are going to use some predefined functions to count the number of unique elements in a given string using python. Find the first repeated word in a string javascript See your article appearing on the GeeksforGeeks In standard SQL, as in the example above, JavaScript functions operate on values. To count specific characters in string or count repeated in a string PHP, you can use PHP function substr_count(). characters in a string myparam = ["1", "2"] An efficient approach will be to observe first that there can be a total of 26 unique characters only. Approach : The idea is to take a substring from index 0 to any index i (i starting from 1) of the numeric string and convert it to long data type.Add 1 to it and convert the increased number back to string. Modified 21 days ago. Contribute your code (and comments) through Disqus. The same procedure name is repeated with parameters of different datatypes and parameters in different positions, varying number of parameters is called overloading of procedures. Approach.

This would not require any extra loop to traverse in a hashmap or a string to find the repeated string.
