I need help, I don't know what's wrong with my code, as it is displaying the correct answer but not accepting it???

It does not gives you the correct answer, since this code: if (a <= b) m = a; else m = b; will strictly gives you answer b even if c has lower number than a and b. I suggest you use logical operator "&&". (Yes they don't tell you but it exist). It has the same function as "and" in excel. In Java, it would look like this: if (a <= b && a <= c) m = a;

Dry run your code first. Let's start we give min(1,2,3) in a = 1,b=2,and c = 3 now in min function, m = 0 first if executed which check 1 <=2 thats true your m = 1; now second if executed check 1<=3 thats true hence your m updated its value and m = 1 ; now third if executed check 2 <=3 thats true and here again m updates its value and m = 2; and finally you return m i.e m = 2; thats not true; solution: if(a<=b) // a is smaller than b if yes { if(a<=c)// check is a is also smaller than c or not return a; // if yes then a is smaller than both of the given number then return a; else return c;// if not then as a is smaller than b but greater than c means c is smaller than a and c is already smaller than b then return c; } if(b < = a) { if(b<=c)// check is 'b' is also smaller than 'c' or not return b; // if yes then 'b' is smaller than both of the given number then return 'b'; else return c;// if not then as 'b' is smaller than 'a' but greater than 'c' means 'c' is smaller than 'b' and 'c' is already smaller than 'a' then return c; } heres your solution
