Help me to find largest and smallest number from array!

Question

largest and smallest number logic

Answer 1

The logic is simple:
We made two variables and set their values to 0(in my case to the first member of the array). Then used a for loop to loop through the array. (I commented most of this in code btw)
if there is a number greater or less than the value stored in our variables then that value is saved as the new value of the variable.

What's the other help you need?

If you just want to find lowest and highest..

let arr = [ 14, 17, 11,8, 3,2,88];
let biggest = arr[0];
let smallest = arr[0];
for(i = 0; i < arr.length ; i++){
if(arr[i] >= biggest){
biggest = arr[i];
}
if(arr[i] <= smallest){
smallest = arr[i];
}
}

ok thank you Akib Reza

Answer 6

To add to Jays idea:
Check the index of the largest and smallest number and set them to NULL I guess.
I don't know of any function.

Answer 7

Akib Reza do you know any function for retrieving the index of an array element?

thank u so much Jay Matthews

int high=0,low=arr[0];
for(int i=0;i<arr.length;i++)
{
if (arr[i]<low)
low=arr[i];
else
high=arr[i];
}
System.out.println("highest and lowest number are:"+ high +" and " + low);
