- For input vector x, write a function to check whether there exists at most 5 elements in x whose values are less than 7.arrow_forwardWhat is COALESCE function? Give an example for it.arrow_forwardDraw a function to use as your original function and draw a transformed function. Make sure to include what the transformed function is. Include each steparrow_forward
- draw a transformed function. Write down step by steparrow_forwardGiven a function with one vector parameter scores. How should the parameter be defined if scores may by very large and the function will modify the parameter? A) constant, and pass by value B) not constant and pass by value C) not constant and pass by reference D) constant and pass by referencearrow_forwardRedesign the solution using functions. For this lab: 1. You will define a function named main() (LO 1) 2. You will get input in the main function and pass it to the following functions: (LO 2) a. milesToKm() b. FahToCel() c. GalToLit() d. PoundsToKg() e. InchesToCm() 3. Each function will require that you have a local variable to store the result of the calculation. This result will then be displayed using the print statement from within the functionarrow_forward
- Example 2: Let f and g be functions from the set of integers to the set of integers defined by f (x)= 2x+3 and g(x)= 3x+2. What is the composition of f and g, and also the composition of g and f?arrow_forwardWith the following function f (a, b, c, d), apply Hindley-Milner type checking and identify the type for each argument. f(a, b, c, d) = if b = 1 then else f(a,b,c,d) [] apply if a[1](0) then c(1) else c(d) if a[b](0) then c(b) else f(a, b - 1, c, d) def if apply 1 if apply [] apply if apply applyarrow_forward
