How do you count the number of words repeated?
Algorithm
- Define a string.
- Convert the string into lowercase to make the comparison insensitive.
- Split the string into words.
- Two loops will be used to find duplicate words.
- If a match found, then increment the count by 1 and set the duplicates of word to ‘0’ to avoid counting it again.
Which data structure should be used to store frequencies?
A simple hashing technique is to use values as index and frequency of each element as value. We use the stack data structure to store the position of elements in the array. 1) Create a list to use values as index to store frequency of each element.
