competitive-programming's Issues

readString() returns ascii value of string in InputReader.java

Competitive-Programming/src/main/java/main/java/InputReader.java

Line 40 in 0de94d3

stringBuilder.append(c);

I tried type casting this to char because earlier it was returning ascii values of all the characters appended. Works fine now.
