We can use the keys() method of the dictionary to get a list of all the keys in the dictionary and count the total number using len() . We can also pass the dictionary directly to the len() function, which returns the distinct total entries in the dictionary, which is the same as the number of the keys.

2. If count[x] is 1, then store index of x in index[x], i.e., index[x] = i.
3. If count[x] is 2, then remove x from index[], i.e., index[x] = n.

How do you count a number of words in string?

Algorithm

1. Define a string.
2. To counts the words present in the string, we will iterate through the string and count the spaces present in the string.
