여기에 사용자 입력 양의 정수 배열이 제공됩니다. 우리의 임무는 홀수 번 발생하는 숫자를 찾는 것입니다.
예시
Input : A=[2, 4, 7, 7, 4, 2, 2] Output : 2
알고리즘
Step 1: Input Array element. Step 2: Write lambda expression and apply. Step 3: Reduce function over the input list until a single value is left. Step 4: Expression reduces the value of a^b into a single value. Step 5: a starts from 0 and b starts from 1.
