Find and display occurrence of each chracter in a string.

Question

Input : a string that contains several characters.
Output : Frequency (number of times each chracter occurred) of each chracter that is present in the given string.

Sample input : Solo learn
Output : s : 1
o : 2
l : 2
e : 1
a : 1
r : 1
n : 1

Answer 1

intialize an empty object like, string_occurence={}.

Now loop over the string
=>for(item of string)

Then check If that item is already in object =>if (string_occurence[item] ),if yes increment it by one else assign object key with a value of one => string_occurence[item]=1

Finally you can use the following loop with Object.entries method and Some destructuring to print out the items in object

for(const [i,j] of Object.entries(string_occurrence))..

Hopefully this helps ,

Answer 2

Use a Map object or build a dictionary object to store key, value pairs. Use the character as the key. If the character is in the Map object, increment its value by 1 for each time the character repeats in the string otherwise add it to the Map object and set its initial value to 1. Then loop through the Map and output its elements.
