Get real-time assistance for Check Balanced String problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
num = "1234"falseThe sum of digits at even indices is 1 + 3 == 4, and the sum of digits at odd indices is 2 + 4 == 6. Since 4 is not equal to 6, num is not balanced.
num = "24123"trueThe sum of digits at even indices is 2 + 1 + 3 == 6, and the sum of digits at odd indices is 4 + 2 == 6. Since both are equal the num is balanced.
