(Solved Now) Gateoverflow test doubt
In https://gateoverflow.in/343341/Gate-overflow-data-structures-1-11 Suppose $L$ is : 10 → 50 → 20 → 40 → 30 & $K$ is : 4, 1, 5 Wouldn’t the explained algorithm print values: 10 40 30 instead of 40 10 30? Won’t it require an algorithm that searches $L$ one by one for all values of $K$ in $O(nk)$ ?

(Closed) Probability, P&C doubt cleared
Question - If there is a bag that has 2 balls, with the colour of the balls being unknown, what is the probability that both turn out to be blue coloured balls? My doubt - which of the 2 following methods is correct and why : 1) Both balls can either ... : 0 blue balls, 1 blue ball or 2 blue balls as the order of balls doesn't matter here hence $\frac{1}{3}$
