The 2020-10-30: given a positive array arr (i.e., the array elements are all positive, find out the array, a maximum of two elements subtraction, one of the minuend subscript subscript is not less than the reduction, namely out: maxValue=https://bbs.csdn.net/topics/max {arr [j] - arr and j>=I} [I]?

CodePudding user response:

 
Public static void main (String [] args) {
Int [] array=,2,5,7,9 {1}; 
The Integer result=null; 
For (int I=array. The length - 1; I> 0; I -) {
For (int j=I; J>=0; J -) {
Int temp=array [I] - array [j]; 
If (result==null | | resultResult=temp; 
} 
} 
} 

System.out.println(result); 
}

CodePudding user response:

Two for loop can
Int maxV=Inetger. MIN_VALUE;
for(int i=0; iFor (int j=I + 1; jIf (arr [j] - arr [I] & gt; MaxV) maxV=arr [j] - arr [I];
}
}
System. The out. Println (maxV);

CodePudding user response:

If is I realize: first to sort an array, and then the maxvalue
