We use the following code to produce an array called $"$x$"$:

#This is the input np$.$random.seed$(1)$ x $=$ np$.$random.randint$(10,$ size $=(4,4))$ print$($x$)$ #This is the output $[[5,8,9,5],[0,0,1,7],[6,9,2,4],[5,2,4,2]]$

Using this array, a slice is made using the following code. Fill in the blank:

#This is the input x$[$:$4,$ :$\_\_]$ #This is the output array$([[5,8],[0,0],[6,9],[5,2]])$
