My Intention for creating this thread is to help New-bees expecially Python New-bees to Post Coding Problems for others to solve and equally solve problems posted by others thereby Sharpening their Coding Skills...

Challenging another user is allowed if nairaland is ok with it...

I hope to Create a Website for this in the near FUTURE!

Happy Coding EveryOne!!!

Let's start with simple Problems:

Write a function that takes a string as an argument and reverses the string then OutPuts it...

Happy Coding!

Must it specifically be the Python programming language that answers should be in?

@Austinoski from your recent posts on this section, you are looking for ways to improve on your programming skills. I suggest that you check out the following sites
projecteuler.net
topcoder.com
and this
http://www.ntnu.edu.tw/acm/
the all contain problems that would develop your skills.

seconded

Java

String s = "hello";
System.out.println(new StringBuilder(s).reverse().toString());


Python

s = "Hello"
s_reversed = ""

for ch in s:
s_reversed = ch + s_reversed

print(s_reversed)

If we do it in python lang only it will be easier to read and know which code is correct or incorrect..

But if we have enough java, c, c++ etc programmers in the house, then it is ok to solve the problems in those langs..

Happy Coding!!!

Thanks A lot!!!

I think I know python well enough..
Y not test me by giving me problems to solve and then score me urself, I will appreciate that.. Thanks

Python

s = "Hello"
s_reversed = ""

for ch in s:
s_reversed = ch + s_reversed

print(s_reversed)

Brilliant Algorithm!
The Code is tricky, took me some minutes to figure out how you did it..

Below is my version:
Python:[br/]

s = "Hello"
s_reversed = ""
rev_int = 0

for i in range(len(s)):
rev_int -= 1
s_reversed += s[rev_int]

print(s_reversed)

Happy Coding!!!

Okay then,

JavaScript

function reverseStr(str) {
return str.split('').reverse().join('').toString();
}

Code challenge 2: Write a program to print out pascal triangle
| | | | 2 | | 3 3 | | 4 6 4 |
My try with JavaScript:

 function pascalTriangle(rows) {

 var triangle, tier;

 triangle = [[1*1]];
 for (i = 0; i < (rows-1); i+=1) {
 tier = [1];
 for (var k = 1; k < triangle[i].length; k++) {
 tier[k] = triangle[i][k] + triangle[i][k-1];
 }
 tier.push(1);
 triangle.push(tier);
 }
 return triangle;
 }
