Description:
Implement the function unique_in_order which takes as argument a sequence and returns a list of items without any elements with the same value next to each other and preserving the original order of elements.
For example:
uniqueInOrder('AAAABBBCCDAABBB') == ['A', 'B', 'C', 'D', 'A', 'B']
uniqueInOrder('ABBCcAD') == ['A', 'B', 'C', 'c', 'A', 'D']
uniqueInOrder([1,2,2,3,3]) == [1,2,3]
var uniqueInOrder=function(iterable){
//your code here - remember iterable can be a string or an array
let res = [];
for (let i = 0; i < iterable.length ; i++) {
if ( iterable[i] === iterable[i-1]) {
continue;
}
if ( iterable[i] !== iterable[i-1]) {
console.log(i)
res.push(iterable[i])
}
}
return res
}
