java - 数组IntList(java)

Question

Write a method isPairwiseSorted that returns whether or not a list of integers is pairwise sorted (true if it is, false otherwise). A list is considered pairwise sorted if each successive pair of numbers is in sorted (non-decreasing) order.

我编写了以下方法，但它总是返回 true。请在这里需要一些帮助。

public boolean isPairwiseSorted() {
    boolean isFalse=false;
    for(int i = 0; i < size; i+=2){
        if( elementData[i] < elementData[i+1] || size == 0 || size == 1){
            return true;
        }
    }
    return isFalse;
}

Answer 1

if (size == 0 || size == 1)
   return true;

for (int i = 0; i < size - 1; i += 2)
{
   if (elementData[i] > elementData[i+1])
      return false;
}

return true;
