Find the Number Occurring Odd Number of Times in C#
C# Code
|
static void
getOddOccurrence() { int[] arr
= { 2, 3, 5, 4, 5, 2, 4, 3, 5, 2, 4, 4, 2 }; int
length = arr.Length;
for (int i =
0; i < length; i++) { int count
= 0;
for (int j =
0; j < length; j++) {
if (arr[i] == arr[j])
count++; } if
(count % 2 != 0) {
Console.WriteLine("Odd Occurrence number is :- " +
arr[i]);
return; } }
Console.WriteLine(-1); } |
output
Logic 2:-
static void
getOddOccurrence() { int[] arr
= { 2, 3, 5, 4, 5, 2, 4, 3, 5, 2, 4, 4, 2 }; int
length = arr.Length; int res =
0; for (int i =
0; i < length; i++) {
res = res ^ arr[i]; } Console.WriteLine("Odd Occurrence number is :- " +
res); }
