DO NOT USE CHATGPT LIKE SOMEONE DID FOR MY LAST POST SINCE THE ANSWER THAT CHATGPT DOES NOT WORK.(YOU WILL GET DOWN VOTED)

SOLVE THIS USING BACKTRACKING: There is two arrays, numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9] and operators = [+, -, *, /]. If the user input a value such as 77 the output should be one operation that equals 77 for example some operation of 77 are '7+8*9-2/1' or '7+8*9-4/2' or 7+8*9-6/3. It is important that the operators and numbers are never duplicated.
