Binary search find lower bound

WebFirst we specify the case (worst,best, average, etc.) and then we specify O, Ω (upper bound, lower bound) or Θ (tight bounds). For Binary search: In the best case scenario (our initial guess finds the target value): - binary search is Θ (1) and as a result is also Ω (1) and O (1). In the worst case scenario (our target is not in the array) Web1 day ago · Step 1 − Create a function to implement a binary search algorithm. Step 2 − Inside the function, first we find the lower bound and upper bound range of the given array. Step 3 − Run a while loop till LBound<=UBound. Step 4 − Now find the middle value of the given range. And check if the middle value is equal to the key element.
