Explanation

Match arr$1[0]=1234$ with arr$2[0]=2345$

Increment $1$ once to get $2(1$ move$)$

Increment $2$ once to get $3(1$ move$)$

Increment $3$ once to get $4(1$ move$)$

Increment $4$ once to get $5(1$ move$).$

$4$ moves are needed to match $1234$ with

Match arr$1[1]=4321$ with arr$2[1]=3214.$
