double mode(
  1. Array a
)

Return the mode of all elements of the array

Examples

var n = Array([1, 2, 3, 3]);

print(mode(n));

/* output:
3.0
*/

Implementation

double mode(Array a) {
  var maxValue = 0.0;
  var maxCount = 0;

  for (var i = 0; i < a.length; ++i) {
    var count = 0;
    for (var j = 0; j < a.length; ++j) {
      if (a[j] == a[i]) ++count;
    }
    if (count > maxCount) {
      maxCount = count;
      maxValue = a[i];
    }
  }
  return maxValue;
