Can anyone please debug it. It’s supposed to find the determinant of the matrix and the problem is in the second function. I’m a beginner and it’s due soon. I have spent 12+ hours straight on just debugging. TBH I just want someone to give me the fixed code and give a quick and simple how. Whoever can do that will be rewarded $10. The answers are supposed to be ‘The determinant of the matrix in matrix2.txt is 6080The determinant of the matrix in matrix1.txt is -413’heres the assignment lab1(5).pdf . assume that the header is fine as well as all the other parts cause i tested them. #include ‘lab1.h’void findDeterminant(char filename[STRINGSIZE]){        int det = 0;        int i, j;        int matrix[MATSIZE][MATSIZE];        FILE *fp3=fopen(filename, ‘r’);        for (i = 0; i
