How to check if an array contains a pair of numbers whose product is even in TypeScript

Answer 1

// A produce of a pair of integers will always be even if at least 1 of them are even
 
function arrayContainsAPairOfEvenProduct(arr: number[]) {
    let oddCount: number = 0;
 
    for (let i: number = 0; i < arr.length; i++) {
        if (arr[i] % 2 === 0) {
            return true;
        }
    }
 
  return false;
}
 
const arr: number[] = [1, 1, 3, 3, 5, 5, 8, 9, 9, 11]; // 8 * ? = Even
 
console.log(arrayContainsAPairOfEvenProduct(arr));
 
 
  
  
  
/*
run:
  
true
  
*/
