Writing my own linux I / O redirect function '>'

I am writing a redirection function that writes the output of a command to a given file name.

For instance:

echo Hello World > hello.txt will write "Hello World" in hello.txt.

ls -al > file_list.txt will write a list of all file / directory names in the current directory to list.txt file.

My function is still defined as:

int my_redirect(char **args, int count) {
    if (count == 0 || args[count + 1] == NULL) {
        printf("The redirect function must follow a command and be followed by a target filename.\n");
        return 1;
    }
    char *filename = args[count + 1];

    //Concatenates each argument into a string separated by spaces to form the command
    char *command = (char *) malloc(256);
    for (int i = 0; i < (count); i++) {
        if (i == 0) {
            strcpy(command, args[i]);
            strcat(command, " ");
        }
        else if (i == count - 1) {
            strcat(command, args[i]);
        }
        else {
            strcat(command, args[i]);
            strcat(command, " ");
        }
    }

    //command execution to file goes here

    free(command);
    return 1;
}

where args[count]- ">".

How to execute a command given by a line from args[0]to args[count - 1]to a file specified in args[count + 1]?

EDIT

These are the instructions that were given to us:

"Improve your shell by adding a redirection for stdout to the file. Try only after completing the function 1. Parse the line for>, take everything before the command and the first word after the file name (ignore <, →, |, etc.).

1 (stdin 0, stderr 2). , 1 dup2.

int f = open( filename , O_WRONLY|O_CREAT|O_TRUNC, 0666) ;
dup2( f , 1 ) ;

: open, . "
