diagonal difference hackerrank solution code example
Example 1: diagonal difference hackerrank python
prim =0
sec=0
length = len(arr[0])
for count in range(length):
prim += arr[count][count]
sec += arr[count][(length-count-1)]
return abs(prim-sec)
Example 2: diagonal difference hackerrank solution in python
def diagonalDifference(arr):
d1 = sum([arr[x][x] for x in range(len(arr))])
d2 = sum([arr[x][n - 1 - x] for x in range(len(arr))])
return(abs(d1 - d2))
Example 3: diagonal difference hackerrank solution in java 8 using list
public static int diagonalDifference(List<List<Integer>> arr) {
// Write your code here
int leftd=0;
int rightd=0;
int n=arr.size();
for(int i=0;i<n;i++)
{
leftd+=arr.get(i).get(i);
rightd+=arr.get(i).get(n-i-1);
}
int absd=Math.abs(leftd-rightd);
return absd;
}
