functional programming - Writing a scheme function -


How do I write a function that takes a list of scoring functions (which I have already written) and pairs of input In the form of strings (which I am skeptical about writing), and gives a revised list of pairs of strings, where all the optimal strings are added from these inputs in the returned list, run according to the input function.

example input: 

  '("hello" "b_lo") ("hello_" "b_l_o") ("hello" "_blow") ("hello" Example of "shock" example:  
  ("hello" "b_lo") ("hello_" "b_l_o") ("h_e_low" "blog_o_w"))   
) ("Hello" "_blow"))   
  The function takes a list of pairs of strings as it is shown above also takes it in a function It uses this function which takes it as a means of evaluating the list of string pairs . It then gives a list of pairs of string that contains all the pairs of strings, which, as a result, was the highest match score based on the work that was given to evaluate them. In other words, ("hello" "b_lo") ("hello_" "b_l_o") ("hello" â ???? _ blow ")) all had a score of 3, but (" h_e_lo ")? ?? bl_o__wâ ????)) is numbered -12, thus it has been removed from the list.   
 Function to calculate alignemt:  
  (define (four-scorer four 1 four 2) (coned ((four =? Four 1 four 2) 2) ((or (four =? Four 1 # \ _) (four =? # \ _ Four 2)) -2 (define -1) (define (alignment-score s1 s2) (minimum length (minimum (string-length s1) (string-length A Define (give loop (score 0) (index 0)) (if (= index minute-length) score (loop (+ score (four-scorer (string-riff S1 index) (string-referee) S2 index))) (+ index 1))))    
 
 
  
     
  1.  
     Apply maximum score (max (lambda (x) (scoring-throw (car x).) (Cadr x)) Lst)))    
  2.  
     Filter the maximum number of matches and By selecting Lee objects and create a list except rest.  
      Define (pre-score-item-level scoring-funk) (maximum-score (scoring scoring-throw score)) (define (assistant in the outside) (if (empty (Assistant (in CDR)) (Assistant (in CDR)) (Assistant (in CDR)) (Assistant (in the list)) (Assistant (outside in CDR)))))) (Assistant Assistant '()))     
     Get results now. ("Hello" "_blow") ("hello" "flick") ("h_e_llo" "bl_o__w")) Alignment (print (get ("Hello" "B_l_o") ("Hello" -score))

Verilog Error: output or inout port "Q" must be connected to a structural net expression -

I get the error every time, I try to compile. I'm not sure why anyone can help is? I'm new to verilog.

The circuit has the following specifications: The present value of swift SW15-0 on the D2 board should be shown in four hexadecimal four sections of HEX3-0. This part of the circuit will be combination logic. To use an active-less asynchronous reset and KEY1 to use KEY0 as the clock input, you must store SW15-0in in a 16-bit register in the value The register should be enabled to have a 16-bit positive edge, which uses the embedded D flip-flo
