A structure that allows repeated execution of a block of statements is a(n) _____________.
- sequence
- selection
- array
- loop
To find the correct option that allows the repeated execution of a block of statements.
d) loop
Explanation of Solution
Explanation: A loop is a structure. It contains one or more than one Boolean expression within the parentheses that returns true or false. The loop body contains a block of statements within the curly braces. If a loop body contains a single statement then it can be written without the use of curly braces. When the Boolean expression of the looping structure returns true then the body of the loop executes. After every iteration (one execution of the loop), the Boolean expression of the looping structure evaluates again. If the Boolean expression of the looping structure returns the true value, the loop body executes again and the Boolean expression of the looping structure Re-evaluated. When the Boolean expression of the looping structure returns the false value, the execution of the loop stopped.
Conclusion: A loop structure allows the repeated execution of a block of statements.

For simplification, only consider cutting the rope at an integer position by the meter metric. Each cut has a cost associated with it, c(m), which is the cost of cutting the rope at position m. (You can call c(m) at any time to return the cost value.) The goal is to cut the rope into k smaller pieces, minimizing the total cost of cutting. B Provide the pseudo-code of your dynamic programming algorithm f(n,k) that will return the minimum cost of cutting the rope of length n into k pieces. Briefly explain your algorithm.

Prove the conjecture that if any problem in NP is not polynomial-time solvable, then no NP-Complete problem is polynomial-time solvable. (You can't use Theorem 1 and 2 directly) 3.

Identify the missing values you think exist in the dataset. Use Column letter and Row number to refer to each missing value in the dataset. Please write down how you want to address each particular missing value (you can group them if they receive same treatment). For imputation, you do not need to calculate the exact imputed values but just describe what kind of value you want to use to impute.arrow_forward
