Question
The "state-space tree" is a conceptual tool often
associated with backtracking. What does it represent?Solution
The state-space tree (or search tree) is a conceptual representation of all possible sequences of choices that an algorithm can make to solve a problem. Each node in the tree represents a partial solution, and the branches represent the possible choices to extend that solution. Backtracking explores this tree, pruning branches that don't lead to a valid solution.
800 + 900 X (3)-2 - ? = 25 X 60 ÷ 2Â
360 ÷ 9 + 15 % of 200 + ? * 10 = 45 * √25
135.37 – 50.24 + 629.09 – 199.50 = ? – 214.68 + 42.65
(0.125)³÷ (0.25)² x (0.5)² = (0.5)?-3
55% of ? = 45 + 20 × 6
13 X √? + 256 ÷ 4 = 30% of 900 - 50
Simplify the following expression:
  (525 +175) ² - (525 – 175) ² / (525 × 175)
The value of 97 × 103 is _________.
What will come in the place of question mark (?) in the given expression?
(?3 - 888) ÷ 4 + 70 = 345 - 65
