Lost card. You have a set of cards numbered from 1 to N. One card is missing. Given the number N followed by N1 distinct integers representing the numbers on the remaining cards, determine and print the number on the missing card.

N = int(input()) total_sum = N * (N + 1) // 2 remaining_sum = 0 for _ in range(N  1): remaining_sum += int(input()) print(total_sum  remaining_sum) 
 Reading Input:
 The
input()
function reads a line of text from the user.
 The
int()
function converts this input to an integer and stores it in the variable N
.
 Calculating Total Sum of All Cards:
total_sum = N * (N + 1) // 2
 The total sum of the numbers from 1 to N is calculated using the formula $2N×(N+) $.
 Calculating Sum of Remaining Cards:

remaining_sum = 0 for _ in range(N  1): remaining_sum += int(input()) 
 Initialize
remaining_sum
to 0.
 Use a
for
loop to iterate N  1
times, reading the remaining card numbers and summing them up.
 Finding the Missing Card:
print(total_sum  remaining_sum)
 The missing card number is found by subtracting
remaining_sum
from total_sum
.
 The result is printed.
