Which of the following is the greatest? \[ 0.6, \ 0.666, \ \frac{5}{6}, \ \frac{2}{3} \]
To compare repeating and terminating decimals, convert them to fractions and compare their values.
0.6
0.666
\( \frac{5}{6} \)
\( \frac{2}{3} \)
Step 1: Convert the decimals to fractions
- 0.6 is equivalent to \( \frac{2}{3} \).
- 0.666 is already a terminating decimal and equals \( \frac{2}{3} \).
- \( \frac{5}{6} \) is in its simplest fractional form.
- \( \frac{2}{3} \) is also in its simplest form.
Step 2: Comparison
- \( 0.6 = \frac{2}{3} \), which is less than 0.666.
- 0.666 is slightly greater than \( \frac{2}{3} \), and is the greatest among the values listed.
Thus, the correct answer is (B).
A meld operation on two instances of a data structure combines them into one single instance of the same data structure. Consider the following data structures:
P: Unsorted doubly linked list with pointers to the head node and tail node of the list.
Q: Min-heap implemented using an array.
R: Binary Search Tree.
Which ONE of the following options gives the worst-case time complexities for meld operation on instances of size \( n \) of these data structures?
