Guava强大的函数式编程接口,如Function和Predicate,也可以与Range结合使用。这种结合使得Range在复杂的数据处理和转换操作中更加灵活。 比如,咱们可以结合使用Predicate和Range来创建复杂的过滤条件: Predicate<Integer> inRange = validRange::contains; List<Integer> evenNumbersInRange = numbers.stream() .filter(inRan...
public static int[] range(int start,int end,int step){ int sz =(end-start)/step; int[] result=new int[sz]; for(int i=0;i<sz;i++) result[i]=start+(i*step); return result; } 这样的话我range(1,10,2),得到的是{1,3,5,7}这样的数组, 但我看到python中range的用法是range(1,...
print(f”The range() function uses {size_r} bytes of memory.”) 用python2解释器不了,然而python3.8解释器得到:The range() function uses 48 bytes of memory. ———– import sys xr=xrange(1,10000) size_xr=sys.getsizeof(xr) print(f”The xrange() function uses {size_xr} bytes of memor...
