Static Methods
-
binarySearch(
List< int> arr, int value, [int start = 0, int? end]) → int -
bitCount(
int i) → int -
bitCount32(
int i) → int -
distance(
double aX, double aY, double bX, double bY) → double - @param aX point A x coordinate @param aY point A y coordinate @param bX point B x coordinate @param bY point B y coordinate @return Euclidean distance between points A and B
-
isDigit(
int ch) → bool -
numberOfLeadingZeros(
int i) → int -
numberOfTrailingZeros(
int i) → int -
round(
double d) → int - Ends up being a bit faster than {@link Math#round(double)}. This merely rounds its argument to the nearest int, where x.5 rounds up to x+1. Semantics of this shortcut differ slightly from {@link Math#round(double)} in that half rounds down for negative values. -2.5 rounds to -3, not -2. For purposes here it makes no difference.
-
sum(
List< int> array) → int - @param array values to sum @return sum of values in array
