Answer:

c. The pivot could either be 7 or 9.

Explanation:

When sorting an array of eight integers through quicksort, the first partitioning indicates that either 7 or 9 may serve as the pivot. Observing the array, it is specifically 7 and 9 that occupy their correct positions within the ordered array. All integers preceding 7 and 9 are lesser, and all numbers following them are greater. Therefore, it suggests that the pivot is located between 7 and 9.

Given positive integer numInsects, write a while loop that prints that number doubled without reaching 200. Follow each number w
zubka84 [1067]

Answer:

The code placed where "/*Your solution goes here */" is as follows:

while(numInsects<200) // while loop

       {

            System.out.print(numInsects+" "); // output statement

            numInsects=numInsects*2; // operation to double the value.

       }

Output:

  • If the input is 16, the result is 16 32 64 128.
  • If the input is 25, the result is 25 50 100.

Explanation:

  • The above Java code fills the section designated as "Your solution" and will operate correctly.
  • The program accepts a user input and continues to print double the value until it reaches 200 or more.
  • The while loop evaluates whether the value remains below 200. If so, the operation proceeds; otherwise, it stops.
