UVA Problem 11713 – Abstract Names Solution:


Click here to go to this problem in uva Online Judge.

Solving Technique:

For input of n there will be 2*n lines. Task is to match a pair of lines. The vowels a, e, i, o, u in the strings doesn’t matter. Except these the rest of both strings should match.

That means each character in a index from both strings should match. Their order needs to be same. Except vowels if the match then output is yes. Otherwise the output is no.

 

Important:  Be sure to add or print a new line after each output unless otherwise specified. The outputs should match exactly because sometimes even a space character causes the answer to be marked as wrong answer. Please compile with c++ compiler as some of my codes are in c and some in c++.

UVA Problem 424 – Integer Inquiry Solution:


Click here to go to this problem in uva Online Judge.

Solving Technique:

This problem requires adding integers. The integers are very long, meaning they won’t fit even in long long. So the addition needs to be done using arrays.

It can be solved using integers arrays but my solution uses character array. Code is explained in the comments.

UVA Problem 10035 – Primary Arithmetic Solution

UVA Problem 10035 – Primary Arithmetic Solution:


Click here to go to this problem in uva Online Judge.

Solving Technique:

For this problem two integers less than 10 digits are given. The task is to find how many carry operations occur when adding.

This problem may be solved using strings since input integer is less than 10 digits. It can be solved with out using array. My implementation is using character array to add and count carry operations.
