Question

write the solution of the program by python 3 language :
I need the program using list or string or loops (while and for) or if,elif,else :

Alex got a sequence of n integers a1,a2,…,an as a birthday present. Alex doesn't like negative numbers, so he decided to erase the minus signs from all negative numbers. As a result, he got a sequence of non-negative numbers. Print the resulting sequence.

For example, if the sequence is  1, 5, -3, 4, -7 , after removing the minuses it becomes  1, 5, 3, 4, 7 . If the sequence is  9, -1, 4, -3, -5, 0 , after removing the minuses it becomes  9, 1, 4, 3, 5, 0 .

Input
The first line contains a positive integer n (1≤n≤1000) — the length of the sequence.

The second line contains n space-separated integers a1,a2,…,an (−1000≤ai≤1000) — the elements of the sequence.

Output
Print a single line — the resulting sequence as a list in Python.

Examples
input
5
1 5 -3 4 -7
output
[1, 5, 3, 4, 7]

Answer 1

Code:

n = int(input())    #taking number of integers to take as input
l = input().split()#taking spaced integers as string and splitting them by space
#str.split() splits the string based on space as no argument is given
#and returns a list of strings of splitted string
for i in range(n):  
    l[i] = int(l[i])#converting string to integer in list
    if l[i]<0:      #if the integer is negative
        l[i] *= -1  #mutliplying it with -1 to convert it to positive
print(l)    #printing the list

Output:

=== RESTART: C:\Users\VSNK\AppData\Local\Programs\Python\Python37 5 1 5 -34 -7 [1, 5, 3, 4, 7] >>>|

Each and everything is explained clearly in the comment section of the code.
