Codility –  TapeEquilibrium 문제 풀이 (난이도 : 하)

// you can also use imports, for example:
// import java.util.*;

// you can write to stdout for debugging purposes, e.g.
// System.out.println("this is a debug message");

class Solution {
    public int solution(int[] A) {
        // write your code in Java SE 8
        
        int front = 0;
        int back = 0;
        for(int i = 0 ; i < A.length ; i++){
            back += A[i];   
        }
        
        int minDiff = Integer.MAX_VALUE;
        int p = 1;
        for(int i = 1 ; i < A.length ; i++){
            front += A[i-1];
            back -= A[i-1];
            p = i;
            minDiff = Math.min(minDiff, Math.abs(front - back));
        }
        
        return minDiff;
        
    }
