        print "Program to find the sum of N numbers"
        arrnumbers = []
        n = 0
        a = 0
        sum = 0
        
        print "Total Numbers:", 
        n = input()
        
        for i in range (0, n):
           print "Enter", i + 1, "Number: ", 
           a = input()
           arrnumbers.append(a)
           sum += a
        
        print "The sum of numbers: [", 
        for i in range (0, n):
           print arrnumbers[i],  
        
        print " ] is: ", sum
        
		#sample output
		#Program to find the sum of N numbers
		#Total Numbers: 5
		#Enter 1 Number:  10
		#Enter 2 Number:  30
		#Enter 3 Number:  20
		#Enter 4 Number:  40
		#Enter 5 Number:  50
		#The sum of numbers: [ 10 30 20 40 50  ] is:  150
