Solve the following python programming problem given the following code:
def fold_infinite(ctx, f, intervals) : 
    if (len (intervals) < 2) : 
        return f 
dim1 = intervals [(- 2)] [0] 
    dim2 = intervals [(- 1)] [0] 
    def g(* args) : 
        args = list (args) 
        n = int (args [dim1]) 
        s = ctx.zero 
        args [dim2] = ctx.mpf (n) 
        for x in xrange ((n + 1)) : 
            args [dim1] = ctx.mpf (x) 
            s += f (* args) 
args [dim1] = ctx.mpf (n) 
        for y in xrange (n) : 
            args [dim2] = ctx.mpf (y) 
            s += f (* args) 
return s 
return fold_infinite (ctx, g, g [: (- 1)]) 

    
    

    Fix the buggy line: return fold_infinite (ctx, g, g [: (- 1)])

#Here is Python program to fix the buggy line: return fold_infinite (ctx, g, g [: (- 1)])
.

return fold_infinite (ctx, g, intervals [: (- 1)])
