#Description
It's the year 2095. In an interesting turn of events, it was decided 50 years ago that BASIC is by far the universally best language. You work for a company by the name of SpaceCorp, who has recently merged with a much smaller company MixCo. While SpaceCorp has rigorous formatting guidelines, exactly 4 space per level of indentation, MixCo developers seem to format however they please at the moment. Your job is to bring MixCo's development projects up to standards.
#Input Description
You'll be given a number N, representing the number of lines of BASIC code.
Following that will be a line containing the text to use for indentation, which will
be ···· for the purposes of visibility. Finally, there will be N lines of
pseudocode mixing indentation types (space and tab, represented by · and » for visibility)
that need to be reindented.
Blocks are denoted by IF and ENDIF, as well as FOR and NEXT.
#Output Description
You should output the BASIC indented by SpaceCorp guidelines.

#Challenge Output
VAR I
FOR I=1 TO 31
····IF !(I MOD 3) THEN
········PRINT "FIZZ"
····ENDIF
····IF !(I MOD 5) THEN
········PRINT "BUZZ"
····ENDIF
····IF (I MOD 3) && (I MOD 5) THEN
········PRINT "FIZZBUZZ"
····ENDIF
NEXT
#Bonus
Give an error code for mismatched or missing statements. For example, this has a missing ENDIF:
FOR I=0 TO 10
····IF I MOD 2 THEN
········PRINT I
NEXT
This has a missing ENDIF and a missing NEXT:
FOR I=0 TO 10
····IF I MOD 2 THEN
········PRINT I
This has an ENDIF with no IF and a FOR with no NEXT:
FOR I=0 TO 10
····PRINT I
ENDIF
This has an extra ENDIF:
FOR I=0 TO 10
····PRINT I
NEXT
ENDIF
