Write a LC$3-$program to do a linear search for a key in an unsorted array. The number to search can be found at label key

and should be stored in register R$1.$ The number of elements in the array, found at label n

should be loaded into register R$2,$ and the address of $($the start of$)$ the array, given by label data

$,$ should be stored in register R$3.$ Your program should determine the position of the key in the array $($ which is a value between $0$ to n$1)$ if it exists and store this position in register R$0.$ If the key is not in the array, store $-1$ in register R$0.$

You can use the following of LC$-3$ code as a starting point for your program. When handing in$,$ use the data provided in the template. You DO NOT need to validate your inputs $($that is$,$ assume the inputs are valid$)$
