Doubt in activity

[Rishika Singh]

Below is a list of real numbers:
√3,2.53,2.5,e,√49,7,22,π,−35,√6,1729,−20000 

How many integers are there in the given list? 

for this ques the ans given is 5 but root 49 is also an integer isn't it?

so ans should be 6, right?

Hey, total integers are root 49=7, 22,-35,1729,-20000.

so total only 5

[Rishika Singh]

but there's both root 49 and 7 written in ques. So they should be counted separately.

The unmodified list will have "6 counts" of "integer", since the question asks one to count the number of integers in the list. (did not ask for unique integers' count)

[Christopher Raphael]

let listOfReals = [ √3, 2.5, e, √49, 7, 22, pi, -35, √6, 1729, -20000 ];
let numberOfElementsInList = listOfReals.length; //=>length of the array = 11
let integerCount=0;

for(i=0; i<numberOfElementsInList; i++)
 {
  if(listOfReals[i]==INTEGER)
   {
   integerCount++;
   }
 }

Result> integerCount: 6
Because √49=7 and therefore will be counted as an integer.

Hi,

    You are right, there are 6 integers in the given list. But now, we have corrected the list. Thank you

Warm regards
