Find the number of elements that are repeated in a given list of numbers and display the number and it's frequency.

For example, if L$=[2,3,2,5,7,3,5,9,2,7,7,7,11]$ then the output is:

$2$: $3$

$3$: $2$

$5$: $2$

$7$: $4$

Only repeated numbers and their frequencies should be printed out.

Hint: Steps that can help to solve this problem.

Step $1.$ Start reading the numbers using a for loop

Step $2.$ Create list of lists.

Step $3.$ Create a new list for every new number read from the original list

Step $4.$ Append the new number to the newly created list.

Step $5.$ Store all lists into one single list as follows.

Step $6.$ For each new number read from the data, check if it exists in any of the lists discovered so far.

Step $7.$ If it exists, append that number to its list.

Step $8.$ Otherwise, go to Step $3$

Step $9.$ If all numbers are done, iterate over the list of lists and check those lists that have length of more than $1($using len$()$ function$).$

Iterating of a list of lists can be done in the same way as iterating any other list, each time the target variable will be set to a new list.

#Sample code to get started

#this is list of lists

List$\_$of$\_$lists$=$list$()$

#list for a new number where a new number is stored

new$\_$number$\_$list$=$list$()$

#append the new number to the list

new$\_$number$\_$list.append$($new$\_$number$)$

#append the new$\_$number$\_$list to the list of lists

List$\_$of$\_$lists.append$($new$\_$number$\_$list$)$

Do not use maps, sets, dictionaries or any other data structures that are not covered in class so far.
