Just make a for loop from l to r, i for example. Then you should check if i / k is between x and y and also if i / k is an integer (people who didnt check this were hacked). If this statement will be true at least once then answer is "YES", otherwise "NO".
Okay Thanks
Thanks :D
A simple linear search in [x, y] (the given range for the cost)
If, for at least one value , i * k (where k is the efficiency required) lies in the range of the experience ie. [l, r], the answer is "YES" otherwise "NO". Time complexity of this solution is O(y - x)
I didn't learn linear search , is it the reason that I can't solve the problem ?
Linear search is just loop/search which works in linear time, what to learn here? :D
Okay , I thought it as binary search that need to learn
