CREATIVE SOLUTIONS FOR FIRST NON-REPEATING CHARACTER DOJO

DOJO Links:

Solution by Manisha/Sveta, modified for case-insensitive test cases

checks if a character is non-repeating by looking for the 2nd match in a string and ensuring that this 2nd match exists. Based on String.prototype.indexOf (check the second usage in the Syntax section on MDN).

A COUNTRY CALLED GHANA

Ghana is a very peaceful but crazy place to live. Ghana is a country in the West Africa, where the people living in are black and are called Ghanaians. It was first named GOLD COST, because it was blessed with gold and was full of natural resources, Ghana gained her independence on 6th March 1957.

The first president to govern ghana was Osagyefo Dr Kwame Nkrumah. The common language spoken in ghana is English but the traditional or local language in ghana is Twi, there are many dishes in ghana but the best and popular dish in ghana is Fufu, fufu is a dish made from cassava and yam or plantain together, the ghanaian dance is called "Adowa", and the ghana popular costume is "Kente". Ghana is a country ruled with written constitution and every four years election takes place to select a new president. Ghana has many political parties but the most popular parties which has ruled the country for the past 24 years are National Democratic Congress (NDC) and New Patriotic Party

You can do this either by using a public service like https://mermaid.ink or while hosting your own mermaid server. I find the latter option to be better in the long run, both in the individual and the collective sense. Below are recipes for both.

Using mermaid.ink

Use the following function defintion in your Jupyter notebook:

import base64
from IPython.display import display_svg
from urllib.request import Request, urlopen

	// Challenge one: Add all the numbers in array
	array.reduce((a, e) => a + e);

	// Challenge two: Create a string with all the numbers stitched in one string
	array.join('')
	array.reduce((a, e) => `${a}${e}`)
	array.reduce((a, e) => '' + a + e);
	array.reduce((a, e) => a + e.toString(), '');
	array.reduce((a, e) => a + e, '');
	array.reduce((a, e) => a.toString() + e.toString());

	if [ $# -ne 5 ] && [ $# -ne 4 ]; then
	echo "Usage: `basename $0` <github_user> <github_repo> <branch> <dest_dir> [<repo_dir>]"
	echo
	echo "if <repo_dir> is omitted then the entire repo archive is unpacked into <dest_dir>"
	exit 0
	fi

	DEST_DIR=./$4
	SOURCE_URL=https://github.com/$1/$2/archive/refs/heads/$3.tar.gz
	if [ $# -ne 5 ]; then

	apt update
	# This is up to you if you would like to apply all updates
	apt upgrade
	# These are the extra dependencies I needed
	# You can see if you are successful without them
	apt install gnupg libcurl4 libncurses5 libxslt1-dev libgpm2 libtinfo5
