Problem:
Given three ints, a b c, return true if one of b or c is "close" (differing from a by at most 1), while the other is "far", differing from both other values by 2 or more. Note: Math.abs(num) computes the absolute value of a number.
closeFar(1, 2, 10) → true
closeFar(1, 2, 3) → false
closeFar(4, 1, 3) → true
Solution:
public boolean closeFar(int a, int b, int c) {
if (Math.abs(a - b) <= 1 && Math.abs(a - c) >= 2 && Math.abs(b - c) >= 2){
return true;
} else if (Math.abs(a - c) <= 1 && Math.abs(a - b) >= 2 && Math.abs(b - c) >= 2){
return true;
}else{
return false;
}
}
public boolean closeFar(int a, int b, int c) {
ReplyDeletereturn !close(b,c)&(close(a,b)^close(a,c));
}
public boolean close(int a, int b) {
return Math.abs(a-b)<=1;
}
return Math.abs(a-b)<=1 && Math.abs(a-c)>=2 && Math.abs(b-c)>=2 || Math.abs(a-c)<=1 && Math.abs(a-b)>=2 && Math.abs(b-c)>=2;

What does the question want us to do? Really confusing
ReplyDeletedont confuse .. its the easiest. if you want answer ,. i can tell you.
Deletepublic boolean closeFar(int a, int b, int c) {
ReplyDeleteint distAB = Math.abs(a - b);
int distBC = Math.abs(b - c);
int distAC = Math.abs(a - c);
if ((distAB <= 1 && distBC <= 1) || (distAB <= 1 && distAC <= 1) || (distBC <= 1 && distAC <= 1)){
return false;
}
return true;
}
boom, boom, boom, boom, I want you in my room!
