Doubt regarding Quick sort

#1

Why is the base case is low >= high
It can be even low == high , even this should work right .
But when i am keeping the base case as low == high , i am getting exception like StackOverflow .
Can you explain me why ?

hi @light007
there will be a possibility when right cross left inside the while loop so in that case you code will run into infinte loop.
