Step 1: Understand the Problem
We need to find how many vowels (a, e, i, o, u) are present in a given string.
Both uppercase and lowercase vowels should be counted.
Non-alphabet characters are ignored.
Step 2: Initialize a Counter
Start by creating a variable, say count, and set it to 0.
This variable will keep track of the number of vowels found in the string.
Step 3: Traverse the String
Loop through each character of the string one by one.
In most languages, you can use a for loop or equivalent iteration.
Step 4: Check if the Character is a Vowel
For each character, check if it is one of a, e, i, o, u or A, E, I, O, U.
If it is, increment the count by 1.
Step 5: Return or Print the Result
After the loop ends, count will contain the total number of vowels.
Print or return this value as the output.
Step 6: Example Walkthrough
Input: "OpenAI"
Process:
'O' → vowel → count = 1
'p' → not a vowel → count = 1
'e' → vowel → count = 2
'n' → not a vowel → count = 2
'A' → vowel → count = 3
'I' → vowel → count = 4
Output: 4

Step 1: Understand the Problem
We need to reverse the order of characters in a given string.
Spaces, uppercase/lowercase letters, and special characters should remain in their positions relative to the string—they are not removed, just reversed.
Step 2: Initialize an Empty Result
Create an empty string (or a character array) to store the reversed version of the string.
Step 3: Traverse the String Backwards
Start from the last character of the original string and move towards the first character.
In most programming languages, this can be done using a for loop that decrements the index from length-1 to 0.
Step 4: Append Characters to Result
For each character in the backward traversal, add it to the empty result string.
Step 5: Return or Print the Result
After the loop ends, the result string will contain the reversed string.
Print or return this string as output.
Step 6: Example Walkthrough
Input: "OpenAI"
Process:
Start from last character 'I' → result = "I"
Next character 'A' → result = "IA"
Next 'n' → result = "IAn"
Next 'e' → result = "IAne"
Next 'p' → result = "IAnep"
Next 'O' → result = "IAnepO"
Output: "IAnepO"
