두 개의 정렬된 배열이 주어지면 출력에 흔하지 않은 요소가 표시되어야 합니다.
Given : array1[]= {1, 4, 6, 9, 12} array2[]= {2, 4, 7, 8, 9, 10} Output : 1 2 6 7 8 10 12
알고리즘
START Step 1 -> declare two arrays array1 and array2 with elements as int and variables n1, n2, i to 0 and j to 0 Step 2 -> calculate number of elements in array1 sizeof(array1)/sizeof(array1[0]) Step 3-> calculate number of elements in array2 sizeof(array2)/sizeof(array2[0]) Step 4 -> Loop While till i<n1 and j<n2 IF array1[i]<array2[j] Print array1[i++] End IF ELSE If array1[i] > array2[j] Print array2[j++ ] End ELSE IF ELSE i++ and j++ End ELSE Step 5 -> End Loop While Step 6 -> loop While i < n1 && array1[i]!=array2[j] Print array1[i++] Step 7 -> End Loop While Step 8 -> loop While j < n2 && array2[j]!=array1[i] Print array2[j++] Step 9 -> End Loop While STOP
