Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. For example, Given input array A = [1,1,2], Your function should retur...

#Retrieve the duplicate values We can also use the filter method to retrieve the duplicate values from the array. We can do this by simply adjusting our condition like so: constarray=['🐑',1,2,'🐑','🐑',3];array.filter((item,index)=>array.indexOf(item)!==index);// ['🐑'...
