Answer 1

list1 = [1, -2, 3, -4, -5, 6]
l = len(list1)
total  = 0;


size  = l
for i in range(1, size):
    
    count = 0;
    if list1[i] < 0:
        x = list1.index(list1[i])
        
        if x ==0:
            list1[1] = list1[0]
       
        for row in range(x, -1, -1):
             
            if list1[row] > 0:
                list1[i] = list1[row]
                break
            else:
                list1[i] = list1[i]
                
           
print(list1)
