Rewrite the following code WITHOUT USING THE string.h library . The output should stay the same

Please provide a screenshot of the code .

#include

int my_function(char classroom[][6], int num_row, char lst[]){

int flag = 0;

int num_col = 6;

int index = 0;

for(int i = 0; i < num_row ; i++){

for(int j = 0; j < num_col;j++){

if(classroom[i][j] == 'X')

{

continue;

}

else{

//check left

if(j-1 >=0 && classroom[i][j-1]!='X'){

lst[index++] = classroom[i][j];

flag = 1;

continue;

}

//check right

if(j+1 < num_col && classroom[i][j+1] != 'X'){
