Question 1
Given a list L write a program to make a new list to fix the indexes of numbers to in list L to its same value in the new list. Put 0 at remaining indexes. Also print the elements of the new list in the single line. (See explanation for more clarity.)
Input:
[1,5,6]
Output:
0 1 0 0 0 5 6
Explanation:
List L contains 1,5,9 so at 1,5,9, index of new list the respective values are put and rest are initialized as zero.

Solution:

``````K=[0]*(max(L)+1)
for i in range(len(K)):
if i in L:
K[i]=i
print(*K,end="")``````

Question 2
Ram shifted to a new place recently. There are multiple schools near his locality. Given the co-ordinates of Ram P(X,Y) and schools near his locality in a nested list, find the closest school. Print multiple coordinates in respective order if there exists multiple schools closest to him. Write a function closestSchool that accepts (X ,Y , L) where X and Y are co-ordinates of Ram’s house and L contains co-ordinates of different school.
Distance Formula(To calculate distance between two co-ordinates): √((X2 – X1)² + (Y2 – Y1)²) where (x1,y1) is the co-ordinate of point 1 and (x2, y2) is the co-ordinate of point 2.
Input:
X, Y (Ram’s house co-ordinates)
N (No of schools)
X1 Y1
X2 Y2
.
.
.
X6 Y6
Output:
Closest pont/points to X, Y

Solution:

``````def closestSchool(x, y, L):
min=9999999
distance=list()
for ij in L:
dis=((x-ij[0])**2+(y-ij[1])**2)**0.5
distance.append(dis)
if dis<min:
min=dis
for ij in range(len(distance)):
if distance[ij]==min:
print(L[ij])``````

Question 1

Given a list L write a program to make a new list and match the numbers inside list L to its respective index in the new list. Put 0 at remaining indexes. Also print the elements of the new list in the single line. (See explanation for more clarity.)
Input:
[1,5,6]
Output:
0 1 0 0 0 5 6
Explanation:
List L contains 1,5,9 so at 1,5,9, index of new list the respective values are put and rest are initialized as zero.

Solution:

``````L = list(map(int, input().split()))

m = max(L)
L1 = [0]*(m+1)

for i in L:
L1[i] = i

for i in range(len(L1)-1):
print(L1[i], end=' ')

print(L1[-1])``````
