The function that counts the number of times a vowel exist in a string is as follows:
def count_vowels(string, dictionary):
vowels = 'aeiou'
dictionary = {}.fromkeys(vowels, 0)
for i in string:
if i in vowels:
dictionary[i] += 1
return dictionary
print(count_vowels("trouble", {}))
<h3>Code explanation.</h3>
The code is written in python.
- we defined a function named "count_vowels". The function accept a string and an empty dictionary.
- Then. we store the vowels in a variable vowels.
- The dictionary is used to store the key value pair i.e the vowels and the number of times they appear.
- We looped through the string.
- If any value in the string is in vowels, we increase the dictionary values by 1.
- Then, we return the dictionary.
- Finally, we call the function with it parameters.

Answer:
Sort the list first, then do a bisection search
Explanation:
In bisection search method, we divide the array of numbers in two equal parts. Then we check that the number is exist in first half or second half. It is necessary to perform this operation that array should sorted. This is the fast searching algorithm as compared to Linear search. In linear search Algorithm we have to check every element in the array until we find the required number. The bisection search method is faster as compare to linear search. This follows following steps top complete the operation of searching.
- Sort the array
- Divide the total array in two equal parts
- Check that the required number that we want to search is in first half or second half
- If the number is found in first half then second half of array will be discarded.
- Then repeat step 2 and 3 until not found the required element.
