Getting TLE in RAAVANCH problem!

i submitted a solution in java , but it was getting TLE !! :worried:
for me it was very confusing as i thought my solutionā€™s time complexity is O(N) and as we must print the array so O(N) should be okay !!
so can someone please tell me why TLE occured and how to optimize the solution !?

Use fast IO , even to optimize a little more w.r.t runtime u shoul use Stringbuilder.

The best approach here will be printing the sequence of 0 and X. I mean if K is 3,N=7 and X=5 then print 0 0 5 0 0 5 0
