Please answer all the questions in SECTION A and one question of your
choice in SECTION B. SECTION A 1. Sort the below dictionary/array key using
Javascript and output the information in key:value format on a Polymer
interface. The entire numeric key should be sorted in an ascending order
and all the alpha keys should be sorted in ascii, ascending order. (10 pts)
Dictionary = {„34‟: ‟thirty-four‟, „90‟: „ninety‟, „91‟: „ninety-one‟„21‟:
„twenty-one‟, „61‟: „sixty-one‟, „9‟: „nine‟, „2‟: „two‟, „6‟: „six‟, „3‟:
„three‟, „8‟: „eight‟, „80‟: „eighty‟, „81‟: „eighty-one‟, „Ninety-Nine‟:
‟99‟, „nine-hundred‟: „900‟,}
NB: The code snippet should be deployed using one of the two options below:
a. A HTML5 cross-platform mobile application using Cordova. Use of
standalone deployments like Node.js or Chrome execution deployments is
accepted.
b. A Django application on apache/nginx webserver and NOT the development
server. This should also be deployed on a red-hat based Linux environment,
preferably (CentOS)
c. An Android java application with an executable APK build
