How to multiply the elements of a list diagonally?-CodePudding

List a = [2,3,4];
List b = [5,6,7];

I want to print 2x7, 3x6, and 4x5

CodePudding user response：

b = b.reversed.toList();
for(int i = 0 ; i < a.length ; i  )
{
  print(a[i] * b[i]);
}

CodePudding user response：

final a = [2, 3, 4];
final b = [5, 6, 7];

for (var i = 0; i < a.length; i  ) {
    final result = a[i] * b[a.length - i - 1];

    print('${a[i]} * ${b[a.length - i - 1]} = $result');
}

Try below code

void main() {
  List a = [2, 3, 4];
  List b = [5, 6, 7];
  for (int i = 0; i < a.length; i  ) {
    print(a[i] * b[a.length - i - 1]);
  }
}
