Given a string str containing only lowercase characters. The task is to print the characters along with their frequencies in the order of their occurrence in the given string.
Input: str = “geeksforgeeks”
Output: g2 e4 k2 s2 f1 o1 r1
Input: str = “helloworld”
Output: h1 e1 l3 o2 w1 r1 d1
Approach: Traverse the given string character by character and store the frequencies of all the strings in a LinkedHashMap which maintains the order of the elements in which they are stored. Now, iterate over the elements of the LinkedhashMap and print the contents.
Below is the implementation of the above approach:
g2 e4 k2 s2 f1 o1 r1
- Print characters and their frequencies in order of occurrence
- Print characters having odd frequencies in order of occurrence
- Print characters having even frequencies in order of occurrence
- Print characters having prime frequencies in order of occurrence
- Print characters and their frequencies in order of occurrence using Binary Tree
- Print 2-D co-ordinate points in ascending order followed by their frequencies
- Print the last occurrence of elements in array in relative order
- Print characters in decreasing order of frequency
- Print common characters of two Strings in alphabetical order
- Print all distinct characters of a string in order (3 Methods)
- Python code to print common characters of two Strings in alphabetical order
- Queries for frequencies of characters in substrings
- XOR of Prime Frequencies of Characters in a String
- Check whether the frequencies of all the characters in a string are prime or not
- Sum and Product of Prime Frequencies of Characters in a String
