at that all elements equal to ak + 1 and ak - 1 also must be deleted from the sequence. That step brings ak points to the player…

sir in this question we remove arr[i],arr[i]-1,arr[i]+1 or we remove index element arr[i],arr[i-1],arr[i+1]

#2

we remove arr[i], and all the elements equal to arr[i]-1 or arr[i]+1 in the array…

thanks
