Write an assembly language program in YASM x86-64 to convert tetradecimal/ASCII base 14 string to integers base 10 and integers base 10 to tetradecimal/ASCII base 14 strings. Using the provided main, the program has four steps are follows:

1. Write the code to convert a string of ASCII digits representing an tetradeciaml value into an integer (double-word sized). This code should be placed in the provided main at the marked location (step #1) and will convert the string dStr1 (tetradecimal representation) into an integer stored in the variable iNum1.

; ----- ; STEP #1 ; Convert tetradecimal/ASCII NULL terminated string at 'dStr1' ; into an integer which should be placed into 'iNum1' ; Note, 12a4D (base-14) = 45,933 (base-10) ; DO NOT USE MACRO HERE!! ; YOUR STEP #1 CODE GOES HERE

 ; ----- ; Perform (iNum1 * 3) operation. ; Note, 45,933 (base-10) * 3 (base-10) = 137,799 (base-10) mov eax, dword [iNum1] mov ebx, 3 mul ebx mov dword [iNum1], eax
