An array is a special array if −
--All the elements at odd indices are odd. --All the elements at even indices are even.
We are required to write a JavaScript function that takes in an array and checks if its a special array or not.
Example
Following is the code −
const arr = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
const isSpecial = (arr = []) => {
for(let i = 0; i < arr.length; i++){
if(arr[i] % 2 === i % 2){
continue;
};
return false;
};
return true;
};
console.log(isSpecial(arr));Output
Following is the output in the console −
true
