The pseudocode to find the sum of all integers that are multiples of 9, from 1 to 250.
totalSum = 0
for i from 1 to 250{
if i is divided by 9 and remainder is 0{
totalSum = totalSum + i;
}
}
print(totalSum)
in python language the code will be
totalSum = 0
for i in range(1,250):
if i%9==0:
totalSum += i
If you will run the program , the answer would be 3402.
