<?php fscanf(STDIN, "%d\n", $test); while($test--) { $ooo=array(); for($i=0;$i<26;$i++) $ooo[$i]=0; fscanf(STDIN, "%s\n", $raa); $qwe=0; $p=strlen($raa); for($i=0;$i<$p;$i++) { $w=ord($raa[$i]); $qwe= $w-97; $ooo[$qwe]=$ooo[$qwe]+1; } $f=0; $c=0; for($i=0;$i<26;$i++) { if($ooo[$i]%2!=0) { $f=1; $c++; } } if($f==0) { echo"Yes"; } else if($f==1 && strlen($raa)%2==1 && $c==1) { echo "Yes"; } else { echo "No"; } echo "<br>"; }

          Getting Started With MEAN App Development I Started Learning AngularJs one year Back. It is always a nice experience to start learning something new. I used Some of my AngularJs skills in my Programming Calculator App. ( https://nikhilnihal.github.io/programmingcalculator/index.html ) Few Days Back , I Started my hands on NodeJs and ExpressJs. I watched many Youtube Videos and Tutorials of  NodeJs and ExpreesJs. After that , I thought to do a Small Project Using all my skills of AngularJs , NodeJs ,ExpressJs.  I followed a Youtube Video ( https://www.youtube.com/watch?v=kHV7gOHvNdk ) and Made a Small Project Similiar to this one.After that I also Learnt that how to deploy my MEAN app on heroku website( heroku.com ). My app uses MongoDB for database. So , i also used mLab ( https://mlab.com /),which provided me MongoDB hosting service. There is a very useful blog which helped me to learn how to deploy my app on heroku. ( ht...
