Write a program $($IN POWERSHELL$)$ to encode numbers in a given string using the algorithm called "Jump the Five." This algorithm is based on a US telephone keypad, where each number is swapped with another based on the mapping:

$1$ becomes $9$

$2$ becomes $8$

$3$ becomes $7$

$4$ becomes $6$

$5$ becomes $0$

$6$ becomes $4$

$7$ becomes $3$

$8$ becomes $2$

$9$ becomes $1$

$0$ Becomes $5$

Here, the task was to make sure the program encoded only numbers in the string, let all else$-$the letters and symbols, etc.$-$be left untouchd
