Task $1$: Decrypting a Shift Cipher $($Caesar Cipher$)$

Problem Statement: You need to decrypt a string that was encrypted using a shift cipher $($Caesar cipher$).$

Your Specific Inputs:

Encrypted String: "Xli$Tvstlix$$,$Tiegi$erh$Fpiwwmrkw$Fi$Ytsr$Lmq$-$$Wemh$>$$E$Qywpmq$mw$xli$sri$ ls$ezsmhw$levqmrk$Qywpmqw$ mxl$lmw$xsrkyi$sv$lmw$lerhw$2$$Erh$e$Qylenmv$$,$er$iqmkverx$-$$mw$xli$sri$ ls$kmziw$yt$$,$eferhsrw$-$$epp$ lex$Eppel$lew$jsvfmhhir$2"$

Your Student ID: $437102453$

Key: $4$

Python Code Snippet:def decrypt$\_$caesar$\_$cipher$($input$\_$str$,$ key$)$: decrypted$\_$text $=""$ for char in input$\_$str: if char.isalpha$()$: shift $=$ ord$($char$)-$ key if char.islower$()$: if shift $<$ ord$(\text{'}$a$\text{'})$: shift $+=26$ elif char.isupper$()$: if shift $<$ ord$(\text{'}$A$\text{'})$: shift $+=26$ decrypted$\_$char $=$ chr$($shift$)$ else: decrypted$\_$char $=$ char decrypted$\_$text $+=$ decrypted$\_$char return decrypted$\_$text if $\_\_$name$\_\_=="\_\_$main$\_\_"$: encrypted$\_$string $=""$ key $=4$ print$($decrypt$\_$caesar$\_$cipher$($encrypted$\_$string, key$))$Expected Output: Your code should decrypt the given string using the key provided. The output should be readable English text.
