Solution 1 :
Sports Section
# Read the input page number
page_number = int(input())
# Check if the page is in the sports section
if 8 <= page_number <= 10:
print(“YES”)
else:
print(“NO”)
Solution – Here
6 digit code appear after 69 seconds.
Solution 4 :
Bit Play
def generate_operation_string(N, S):
operation_string = “”
for i in range(N):
index = (i * (i + 1)) // 2
if S[index] == ‘0’:
operation_string += ‘|’
else:
operation_string += ‘^’
return operation_string
T = int(input())
# Process each test case
for _ in range(T):
N = int(input())
S = input().strip()
operation_string = generate_operation_string(N, S)
if operation_string:
print(operation_string)
else:
print(“-1”)
Solution 5:
Array Sum
def generate_array(N, K):
if N % 2 == 0 and K % N == 0 and K >= N:
array = [K // N] * N
return array
else:
return None
T = int(input())
for _ in range(T):
# Read N and K for the test case
N, K = map(int, input().split())
result = generate_array(N, K)
if result:
print(” “.join(map(str, result)))
else:
print(“-1”)
Solution 7 :
Light The Bulb
def count_ways_to_light_bulb(N, initial_switches, desired_bulb):
# Initialize the count of ways to 0
ways = 0
# Iterate through all possible substrings of the initial switches
for i in range(N):
for j in range(i, N):
substring = list(initial_switches[i:j + 1])
# Flip the characters in the substring
for k in range(len(substring)):
substring[k] = ‘1’ if substring[k] == ‘0’ else ‘0’
# Check if the flipped substring matches the desired bulb configuration
if ”.join(substring) == desired_bulb:
ways += 1
return ways
# Read the number of test cases
T = int(input())
# Process each test case
for _ in range(T):
N = int(input()) # Length of switches and bulb configuration
initial_switches = input().strip() # Initial switch configuration
desired_bulb = input().strip() # Desired bulb configuration
# Calculate and print the number of ways to light up the bulb
ways = count_ways_to_light_bulb(N, initial_switches, desired_bulb)
print(ways)
