Problem statement

Given a string “STR”, you need to remove spaces from the string “STR” and rewrite in the Pascal case. Your task is to return the string “STR”.

In the Pascal case writing style we don’t have spaces between words and all words begin with uppercase letters including the first word.

Note:

Input string “STR” will only consist of lowercase English Alphabets. The string will not contain white space at the beginning and end of the string.

Input Format:

The first line of input contains an integer ‘T’ denoting the number of test cases to run. Then the test case follows.

The first and the only line of each test case contains the string 'STR'.

Output Format :

For each test case, return a string that is written in the Pascal case style.

Output for each test case will be printed in a new line.

Note:

You do not need to print anything; it has already been taken care of. Just implement the given function.

Constraints:

1 <= T <= 5
1 <= |STR| <= 10^5

Where |STR| denotes the length of “STR”

Time Limit: 1sec

Approaches

01 Approach

We can iterate over the string “STR” and maintain the resultant string in “answer”. On each character check if that character is white space (‘ ’) then change the next character to uppercase and do not include white space in the string “answer”, else append that character in the string “answer”.

Algorithm:

Create an empty string “answer”.
Iterate over string “STR”, for each character
- If the STR[i] == ‘ ‘:
  - Change STR[i + 1] to upper case.
- Else
  - Append this character in “answer”.
Return “answer”.
